 TIJUANA, Mexico (AP) — With about 3,000 Central American migrants having reached the Mexican border across from California and thousands more anticipated, the mayor of Tijuana said Friday that the city was preparing for an influx that will last at least six months and may have no end in sight. 
  
 Juan Manuel Gastelum said there were 2,750 migrants from the caravan in Tijuana and that estimates by Mexico's federal government indicate the number could approach 10,000. 
  
 "No city in the world is prepared to receive this — if I'm allowed — this avalanche," he said during a news conference at City Hall. "It is a tsunami. There is concern among all citizens of Tijuana." 
  
 U.S. border inspectors are processing only about 100 asylum claims a day at Tijuana's main crossing to San Diego, creating long waits. Asylum seekers register their names in a tattered notebook managed by migrants themselves that had more than 3,000 names even before the caravan arrived. 
  
 Along the nearly 3,000 miles (nearly 5,000 kilometers) from the caravan's origin in San Pedro Sula, Honduras, to this city on the Pacific Ocean, the migrants have stopped in most places for only a single night, with some exceptions. 
  
 That overwhelmed small towns in southern Mexico in particular — but only briefly. The migrants' expected long stay in Tijuana has raised concerns about the ability of the teeming border city of more than 1.6 million to handle the influx. 
  
 Pleading for financial support from the Mexican government, Gastelum sternly warned migrants against criminal behavior, though authorities reported only seven arrests so far — five for drug consumption and two for disorderly conduct. 
  
 "Supposedly they are fleeing catastrophe, mistreatment in their countries of origin. How is it possible that they arrive here and, if they want, create disorder?" the mayor said. "It's not right." 
  
 His language linking the latest arrivals to crime underscores how the caravan is already testing Tijuana's proud history as a melting pot for immigrants, a tradition that Gastelum also highlighted. 
  
 A municipal gymnasium and recreational complex that has been converted to a shelter was expected to register up to 1,000 people Thursday night but ended up housing more than 2,000, including more than 400 children. 
  
 Tijuana officials said they opened the shelter as part of an effort to keep migrants out of public spaces. 
  
 The city's privately run shelters are meant to have a capacity of 700. 
  
 At the municipal shelter, long lines formed for showers and meals of tuna casserole or noodle soup with coffee. Outdoor canopies covered rows of mattresses and blankets. 
  
 A woman singing Mexican "ranchera" music on a loudspeaker drew a small crowd, while men congregated in circles to play cards. Eighteen new portable toilets on a grass field made bathroom lines disappear. 
  
 U.S. President Donald Trump, who sought to make the caravan a campaign issue in last week's elections, took to Twitter on Friday to aim some new criticism at the migrants. 
  
 "Isn't it ironic that large Caravans of people are marching to our border wanting U.S.A. asylum because they are fearful of being in their country — yet they are proudly waving ... their country's flag. Can this be possible? Yes, because it is all a BIG CON, and the American taxpayer is paying for it," he said in a pair of tweets. 
  
 Migrant Ronald Calderon, who picked coffee beans back in Honduras, said he would seek asylum in the U.S. if he felt there was a 90 percent chance of success. But he figures the odds are long and doesn't want to risk being deported, so he hopes to find work and settle in Tijuana. 
  
 "I see that Donald Trump talks about us as criminals and killers, and I don't think an opportunity may present itself," said Calderon, 23. 
  
 Andrea Ramirez, 42, said that her siblings were killed by gangs in Honduras and that she registered her name Friday to seek asylum in the U.S. 
  
 "The only thing we want is not to go back to Honduras," Ramirez said. 
  
 Also Friday, another caravan set out from Mexico City heading toward the border. 
  
 Gastelum, the mayor, wondered why the migrants chose Tijuana instead of other Mexican cities on the U.S. border, vaguely suggesting a sinister plot without elaborating. 
  
 "There is an intention to do things badly. There is an intention to prejudice Tijuana, and we cannot allow that," he said. 
  
 His comments marked a contrast to a more welcoming tone from other officials. Francisco Rueda, the top deputy to Baja California Gov. Francisco Vega de la Madrid, said Thursday that the state had 7,000 jobs available for any migrants who obtain legal status in Mexico. 
  
 Gustavo Magallanes, director of Baja California's migrant attention agency, said Friday that the state is doing the best it can at a difficult time and that, nearing the end of the year, agencies at all levels of government lack funds. 
  
 The governor had also asked federal officials to speak to their U.S. counterparts about possibly accelerating asylum processing, he said. 
  
 Magallanes said the governor had not ordered that more migrants be prevented from arriving in Tijuana, but said state officials were telling people in the caravan they might get processed faster in the city of Mexicali because the list in Tijuana is so long. 
  
 Magallanes said it was "likely" the migrants could be waiting in Tijuana for four to six months. The state government plans to push them to regularize their immigration status in Mexico so they can be offered work. 
  
 He said he could not speak for Tijuana's mayor but believed his comments had been misinterpreted. 
  
 "We are looking for the best way for these Central American migrants ... to be able to be in the best situation in this state," Magallanes said.

 SAN DIEGO (AP) — As thousands of migrants in a caravan of Central American asylum-seekers converge on the doorstep of the United States, what they won't find are armed American soldiers standing guard. 
  
 Instead they will see cranes installing towering panels of metal bars and troops wrapping concertina wire around barriers while military helicopters fly overhead, carrying border patrol agents to and from locations along the U.S.-Mexico border. 
  
 That's because U.S. military troops are prohibited from carrying out law enforcement duties. 
  
 What's more, the bulk of the troops are in Texas — hundreds of miles away from the caravan that started arriving this week in Tijuana on Mexico's border with California after walking and hitching rides for the past month. 
  
 Still, for many migrants the barriers and barbed wire were an imposing show of force. 
  
 Angel Ulloa stood on Tijuana's beach where a wall of metal bars more than 20 feet high cut across the sand and plunged into the Pacific. He watched as crews on the U.S. side placed coils of barbed wire on top. 
  
 A border patrol agent wearing camouflage and armed with an assault rifle — part of a tactical unit deployed when there is a heightened threat — walked in the sand below where the men worked. A small border patrol boat hovered offshore. 
  
 "It's too much security to confront humble people who just want to work," said Ulloa, a 23-year-old electrician from Choloma, Honduras, who joined the caravan to try to make his first trip to the U.S. 
  
 Now, he and his two friends were rethinking their plans. They tried to apply for a job at a Wal-Mart in Tijuana but were told they need a Mexican work permit. So they were considering seeking asylum in Mexico but were unsure of giving up their dream of earning dollars. 
  
 "We're still checking things out," he said. 
  
 On Friday, people walking through one of the world's busiest border crossings into Mexico passed by a pair of Marines on a 20-foot lift installing razor wire above a turnstile. 
  
 Nearby Army Sgt. Eric Zeigler stood guard with another soldier. Both were military police officers assigned to protecting the Marines as they work. 
  
 The 24-year-old soldier from Pittsburgh spent nine months in Afghanistan. ""It's very different over there, obviously. It's a lot more dangerous," Zeigler said. 
  
 He said he was surprised when got his deployment orders sending him to the U.S.-Mexico border. 
  
 "But I'm happy to go where I'm needed" he added as a man walked by carrying shopping bags headed to Tijuana. 
  
 The U.S. military has deployed 5,800 active-duty troops to the U.S.-Mexico border. 
  
 So far, more are not expected, despite President Donald Trump's initial assessment that 10,000 to 15,000 were needed to secure the border against what he has called an "invasion" of migrants. Most in the caravan of several thousand are families, including hundreds of children. 
  
 Another 2,100 National Guard troops are have also been deployed since April as part of a separate mission. Like the military troops, they are not allowed to detain illegal crossers. Instead, they have been monitoring cameras and helping to erect barriers. 
  
 Of the 5,800 soldiers and Marines, more than 2,800 are in Texas, while about 1,500 are in Arizona and another 1,300 are in California. All U.S. military branches, except the Coast Guard, are barred from performing law enforcement duties. 
  
 That means there will be no visible show of armed troops, said Army Maj. Scott McCullough, adding that the mission is to provide support to Customs and Border Protection. 
  
 "Soldiers putting up wire on the border and barriers at the ports of entry will be the most visible," he said. 
  
 Marines and soldiers share the same duties in California and Arizona. These include erecting tents, setting up showers and arranging meals for troops working on the border, and assigning military police to protect them. 
  
 There are no tents or camps being set up to house migrants, McCullough said. Medics are on hand to treat troops and border patrol agents — not migrants — for cuts, bruises and any other problems. 
  
 Combat engineers — whose duties on the battlefield include setting up tactical obstacles to prevent the enemy from moving freely — are using their expertise to string wire on border walls and erect temporary fencing, McCullough said. 
  
 Construction engineers have been assigned to weld together barriers and move shipping containers to act as walls. 
  
 In Laredo, Texas, about 100 soldiers have been installing three layers of razor wire along the Rio Grande, working on the banks during the day and on the bridges at night to minimize the disruption to cross-border traffic. 
  
 The current mission is scheduled to end Dec. 15 for now. It's unclear how much it will cost and military leaders have refused to provide an estimate. 
  
 Critics have questioned the wisdom of using the military on the border where there is no discernible security threat. Since the Nov. 6 elections, Trump has said little about the matter and no border threat has materialized. 
  
 Some border communities fear the barricades will scare off Mexican shoppers. The city council in Nogales, Arizona, slashed a proposed bonus for all employees in half over concerns about how the military's presence would affect its sales tax revenue after the military closed off two lanes at its border crossing. 
  
 Defense Secretary Jim Mattis defended the deployment during a visit to the Texas border this week, asserting that in some ways it provides good training for war. 
  
 Suyapa Reyes, 35, said she was puzzled as to why she would be seen as a threat. Reyes, her mother, 12-year-old daughter and 16-year-old son left Honduras with the caravan on Oct. 13, fleeing violence and poverty in her hometown of Olanchito de Oro. 
  
 She does not want to return after coming such a long way but if she cannot get asylum and the border looks too dangerous to cross, she said she'll have no other choice. 
  
 "I'm not going to risk my life or safety nor that of my children," she said.
