ADDITION TO IDENTIFY OPPOSITION LAWMAKER - Opposition lawmaker Armando Armas lies on the ground covering his head as pro-government militias attack lawmakers and National Assembly employees, in Caracas,... (Associated Press) 
  
 CARACAS, Venezuela (AP) — Pro-government militias wielding wooden sticks and metal bars stormed congress on Wednesday, attacking opposition lawmakers during a special session coinciding with Venezuela's independence day. 
  
 Four lawmakers were injured and blood was splattered on the neoclassical legislature's white walls. One of them, Americo de Grazia, had to be removed in a stretcher while suffering from convulsions. 
  
 "This doesn't hurt as much as watching how every day how we lose a little bit more of our country," Armando Arias said from inside an ambulance as he was being treated for head wounds that spilled blood across his clothes. 
  
 The unprecedented attack, in plain view of national guardsmen assigned to protect the legislature, comes amid three months of often-violent confrontations between security forces and protesters who accuse the government of trying to establish a dictatorship by jailing foes, pushing aside the opposition-controlled legislature and rewriting the constitution to avoid fair elections. 
  
 Tensions were already high after Vice President Tareck El Aissami made an unannounced morning visit to the National Assembly, accompanied by top government and military officials, for an event celebrating independence day. The short appearance at the congress by top officials who have repeatedly dismissed the legislators as a band of U.S.-backed conspirators was seen by many as a provocation. 
  
 Standing next to a display case holding the founding charter, El Aissami said global powers are once again trying to subjugate Venezuela. 
  
 "We still haven't finished definitively breaking the chains of the empire," he said, adding that President Nicolas Maduro's plans to rewrite the constitution — a move the opposition sees as a power-grab — offers Venezuela the best chance to be truly independent. 
  
 After he left, dozens of government supporters set up a picket outside the building, heckling lawmakers with menacing chants and eventually invading the legislature themselves. The siege only lifted after seven nerve-wracking hours when police set up a corridor to allow the hundreds of people trapped inside the legislature, including lawmakers and journalists, to leave. 
  
 The brazen attack on one of the symbols of Venezuela's already limping democracy drew widespread international rebuke. 
  
 "This violence, perpetrated during the celebration of Venezuela's independence, is an assault on the democratic principles cherished by the men and women who struggled for Venezuela's independence 206 years ago today," U.S. State Department spokeswoman Heather Nauert said. 
  
 Despite the violence, lawmakers approved a plan by the opposition to hold a symbolic referendum on July 16 that would give voters the chance to reject Maduro's plans to draft a new political charter. 
  
 Later Maduro condemned the violence, but complained that the opposition doesn't do enough to control "terrorist attacks" committed against security forces by anti-government protesters. 
  
 "I will never be an accomplice to acts of violence," said Maduro during a speech at a military parade. 
  
 The clash followed Tuesday's appearance of two short videos by a former police inspector who allegedly stole a helicopter and fired on two government buildings last week. 
  
 Oscar Perez, repeating a call for rebellion among the security forces, said that he was in Caracas after abandoning the helicopter along the Caribbean coast and was ready for the "second phase" of his campaign to free his homeland from what he called the corrupt rule of Maduro and his "assassin" allies. 
  
 Perez gave no other details but pledged to join youth who have been protesting on the streets the past three months against Maduro. 
  
 "Stop talking. Get on the streets. Take action. Fight," he said in the video, sitting before a Venezuelan flag and with what looks like an assault rifle by his side. He also denounced Maduro's plan to rewrite the constitution. 
  
 "If this constitutional assembly goes through, Venezuela will cease to exist because we'll have given away the country to the Cubans," he said. 
  
 Hours later, another video appeared in which he urged Venezuelans to march on a Caracas military base, not the presidential palace, to locate and remove Maduro along with the ruling elite. 
  
 The bold though largely harmless June 27 attack shocked Venezuelans who had grown accustomed to almost-daily clashes since April between often-violent youth protesters and security forces that have left more than 90 people dead and hundreds injured. 
  
 Perez apparently piloted the stolen police helicopter that sprayed 15 bullets toward the Interior Ministry and dropped at least two grenades over the supreme court building. 
  
 While Maduro claimed Perez had stolen the helicopter on a U.S.-backed mission to oust him from power, many in the opposition questioned whether the incident was a staged by the government to distract attention from the president's increasingly authoritarian rule. 
  
 Adding to the intrigue is Perez's colorful past. 
  
 In 2015, he produced and starred in a film called "Suspended Death," and several photos show him in fatigues, scuba diving while toting an assault rifle, skydiving and standing in action poses with a German shepherd by his side. In his political debut, he read a manifesto in which he claimed to be part of a group of disgruntled members of Venezuela's security forces determined to save the country's democracy. 
  
 Perez said in the video that the strike produced no casualties because he had taken care to avoid them. Neither of the buildings he attacked suffered damage. The helicopter he stole was found 24 hours later, abandoned in a verdant valley near the Caribbean coastline outside Caracas. ||||| CARACAS (Reuters) - Pipe-wielding government supporters burst into Venezuela’s opposition-controlled congress on Wednesday, witnesses said, attacking and besieging lawmakers in the latest flare-up of violence during a political crisis. 
  
 The melee, which injured seven opposition politicians, was another worrying flashpoint in a traumatic last three months for the South American OPEC nation, shaken by opposition protests against socialist President Nicolas Maduro. 
  
 At least 90 people have died in the unrest, with fighting and barricades frequently blocking cities across Venezuela. 
  
 National Assembly president Julio Borges said more than 350 politicians, journalists and guests to the Independence Day session were trapped in the siege that lasted until dusk. 
  
 “There are bullets, cars destroyed including mine, blood stains around the (congress) palace,” he told reporters. “The violence in Venezuela has a name and surname: Nicolas Maduro.” 
  
 The crowd had gathered just after dawn outside the building in downtown Caracas, chanting in favor of Maduro, witnesses said. In the late morning, several dozen people ran past the gates with pipes, sticks and stones and went on the attack. 
  
 Several injured lawmakers stumbled bloodied and dazed around the assembly’s corridors. Some journalists were robbed. 
  
 After the morning attack, a crowd of roughly 100 people, many dressed in red and shouting “Long Live The Revolution!”, trapped people inside for hours, witnesses said. 
  
 Some in the crowd outside the legislature brandished pistols, threatened to cut water and power supplies, and played an audio of former socialist president Hugo Chavez saying “Tremble, oligarchy!” Fireworks were thrown inside.

 The worst-hurt lawmaker, Americo De Grazia, was hit on the head, fell unconscious, and was eventually taken by stretcher to an ambulance. His family later said he was out of critical condition and being stitched up. 
  
 Downtown Caracas is a traditional stronghold neighborhood for the government and there has been a string of clashes there since the opposition thrashed the ruling Socialist Party in December 2015 parliamentary elections. 
  
 In a speech during a military parade for Independence Day, Maduro condemned the “strange” violence in the assembly and asked for an investigation. But he also challenged the opposition to speak out about violence from within its ranks. 
  
 In daily protests since April, young demonstrators have frequently attacked security forces with stones, homemade mortars and Molotov cocktails, and burned property. They killed one man by dousing him in gasoline and setting him on fire. 
  
 “I want peace for Venezuela,” Maduro said. “I don’t accept violence from anyone.” 
  
 FOREIGN CONDEMNATION 
  
 Numerous foreign nations repudiated Wednesday’s events. 
  
 “I condemn the grotesque attack on the Venezuelan assembly,” tweeted UK ambassador John Saville. 
  
 “This violence, perpetrated during the celebration of Venezuela’s independence, is an assault on the democratic principles cherished by the men and women who struggled for Venezuela’s independence 206 years ago today,” the U.S. State Department said.

 Venezuela’s opposition is demanding general elections to end socialist rule and solutions to the OPEC nation’s brutal economic crisis. The government says its foes are seeking a violent coup with U.S. support. 
  
 Earlier, a Venezuelan police officer who staged a helicopter attack on government buildings in Caracas last week appeared in an internet video vowing to continue fighting. 
  
 “Once again we are in Caracas, ready and willing to continue our struggle for the liberation of our country,” police pilot Oscar Perez said in the video, wearing a military uniform and wool cap, with a Venezuelan flag and rifle behind him. 
  
 Perez had not been seen since he hijacked a helicopter last week and flew through Caracas pulling a “Freedom” banner. He opened fire and dropped grenades on the Interior Ministry and Supreme Court but nobody was injured. 
  
 Maduro, 54, the successor to Hugo Chavez, called that attack a terrorist assault to overthrow him and lambasted Western nations for not condemning it. 
  
 But many government critics doubt the official version, and some even suggested it may have been staged to divert attention from the country’s economic and political crises. 
  
 In the video, Perez said the attack was “perfectly achieved” with no collateral damage “because it was planned, because we are not murderers like you, Mr. Nicolas Maduro.” 
  
 Perez said he had staged an emergency landing on the Caribbean coast following the attack, and returned to the capital after hiking through mountains. The Information Ministry did not immediately respond to a request for comment. 
  
 Perez, who has portrayed himself as a James Bond-cum-Rambo figure on social media, also is an actor who starred in a 2015 movie about the rescue of a kidnapped businessman. 
  
 Although he has claimed wider support within the security forces, Perez’s actions so far appear to be a rogue stunt organized by a small group of disaffected policemen.

 Venezuela’s opposition says Maduro is seeking to consolidate control through a Constituent Assembly, a superbody that will be elected at the end of July. The opposition has promised to boycott the vote, which it says is rigged in favor of the ruling Socialist Party. 
  
 Before the attack on them, opposition lawmakers held a session denouncing the president as a “dictator” and approving a plebiscite that the opposition is organizing for July 16, asking Venezuelans what they think of Maduro’s plans. |||||
