Input: Chiang Rai, Thailand (CNN) Families are nervously awaiting news of 12 missing boys and their soccer coach Tuesday as rescuers search a partially flooded cave complex in northern Thailand where the group is thought to have been trapped since the weekend. 
  
 Most of the boys' parents are at a makeshift camp near the Tham Luang Nang Non caves and have not left the area since they learned their children were missing on Saturday. 
  
 "I feel I have just lost my heart because I just found his bag, mobile phone and his shoes. But all I can do is just wait," said Sudsakorn Sudtham, 35, whose son, Prajak, is 14. 
  
 The parents of the missing boys have been at the site near Chiang Rai since Saturday. 
  
 The group, all belonging to the same soccer team from the nearby city of Chiang Rai, have been missing since 1 p.m. Saturday when a park officer spotted something amiss -- bicycles parked idly by the entrance to the cave despite it being off-limits. 
  
 They are believed to have crawled into the large series of caves through a narrow, 15-meter-long (50-foot) channel. 
  
 Another anxious parent, Pinyo Bhodhi, 37, said he became worried when his son, Pipat, 15, hadn't returned home Saturday evening -- the day before his birthday. 
  
 He told CNN he'd arranged a party and a cake for Pipat, a keen soccer player who "trains every day" and has dreams of being on the Thai national team, on Saturday night. 
  
 When Pipat failed to come home, his father started calling around to his son's friends, teammates and coaches. 
  
 "It was already 7 (or) 8 p.m. and he hadn't returned home, (so) I started to look for him." 
  
 Soccer shoes are left next to bikes from the missing boys at the entrance of a cave in northern Thailand. 
  
 When he learned of the boys' disappearance at the caves, he rushed to the scene near Chiang Rai and has been waiting there since Saturday night. He said he discovered his son's bike outside the cave. 
  
 "When I saw his bike parked inside at the cave, my tears were just dropping. I was desperate to find my son. 
  
 "We need a miracle. I want him back." 
  
 He was looking forward to seeing his son blow out candles on his birthday cake, but now "the cake remains at home." 
  
 Pumps used to drain water from cave complex 
  
 The families sit and wait as rescuers battle heavy rains to search the flooded system of caves where the group is thought to be trapped. 
  
 Emergency services are attempting to pump water out of the cave complex after the rain flooded the caves and the passages that link them. 
  
 Rescue teams gather Monday in a deep cave where the group of boys went missing. 
  
 "We (are) drawing out water from the cave, and we're (currently) looking for more water pumps" and long cables with which to power the pumps, said Kamolchai Kotcha, an official with Thailand's national parks authority. 
  
 A team of Thai Royal Navy SEAL divers, who re-entered the cave complex early Tuesday, haven't found any trace of the children or their coach, Kotcha told CNN by phone. 
  
 A bicycle belonging to one of the missing boys is seen outside the cave complex. 
  
 However, Deputy Prime Minister Prawit Wongsuwan said that the government had not ruled out hope of finding the boys and the coach alive. 
  
 "We are still optimistic they are all alive. Even though they may not have anything to eat, they should have water to drink." 
  
 Vernon Unsworth, a spelunker who lives in Chiang Rai, said the conditions in the cave are difficult. 
  
 "The water is rising all the time. Physically it's not a hard cave; it's just very long," he told CNN from the rescue site. 
  
 "I think we just have to wait for the navy SEALs to see what they can do, how far they can go. The conditions further on will not be easy so we just have to wait and (keep our) fingers crossed." 
  
 He said a big pool of water is continually rising in a section of the cave about 3 kilometers (1.7 miles) from the entrance. The "next six to eight hours will be crucial," he said. 
  
 Kotcha of the national parks authority said around 40 chambers are inside the Tham Luang Nang Non cave, "both small and big ones." 
  
 Rescuers suspect the missing boys are still in the main chamber of the cave. 
  
 Thai Interior Minister General Anupong Paochinda said the divers could only work intermittently due to the restrictions of their equipment. He said the rescue team was trying to reduce the water level to prevent it from "reaching the ceiling of the passage" so there's an air pocket for the rescuers. 
  
 "The water is muddy; it has also still blocked the passage (into the chamber). The SEALs have switched from using (an) oxygen tank to a closed-circuit system," which allows them to dive up to three hours at a time. 
  
 "We are arranging more water pumps and electricity cable to drain water. Hopefully we can create some space (at the passage) for them." 
  
 Kotcha said the team is waiting for updates from the SEALs, who are trying to get through the flooded channel. ||||| Image copyright AFP Image caption Navy divers have been sent in to help look for the missing teenagers 
  
 Thailand's deputy PM has said he is optimistic a group of young footballers trapped inside a cave are still alive, as the search enters a third day. 
  
 The boys, aged between 11 and 16, and their coach entered the cave in Chiang Rai province on Saturday. 
  
 Navy divers resumed their efforts on Tuesday after rising waters had halted the search. 
  
 They had reportedly seen fresh footprints inside the cave complex, raising hopes for the group's safety. 
  
 "We are still optimistic they are all alive," Deputy Prime Minister Prawit Wongsuwon said on Tuesday. 
  
 "Even though they may not have anything to eat, they should have water to drink."

 'Families praying'

 Navy divers have been trying to reach the deepest caverns, and turning the area around the caves into a sea of mud. Weary, rain-soaked rescuers can be seen coming to and from the cave entrance, where medical teams are waiting, in the hope that the missing boys may be found. 
  
 Family members pray around makeshift shrines. 
  
 They have brought in pumps to try to reduce the water level, but so far have only been able to use them outside the caves, where their efforts are being thwarted by the rain. They are now reeling power cables into the caves to help the divers with better light, and to use the pumps there. They have also tried using drones. 
  
 So far the only sign of the missing boys is the bicycles they left, which are still locked to the fence at the cave entrance, and some handprints spotted by divers who reached one of the largest underground chambers on Monday. 
  
 How was the team trapped? 
  
 The team and their coach are believed to have entered the Tham Luang Nang Non cave on Saturday afternoon. 
  
 Rescue workers began searching for them on Saturday night after they were reported missing. The search was briefly halted but navy divers were able to re-enter the cave early Tuesday. 
  
 Large squads of soldiers have been brought in to see if they can get access from the hills above the caves. 
  
 There are also dozens of volunteers with more experience of cave diving and exploration. 
  
 According to the Bangkok Post, visitors must cross a small stream to enter the cave, making it inaccessible if the stream floods.

 The cave can flood up to 5m (16ft) during Thailand's rainy season, which runs from June to October. 
  
 Rescue teams were preparing to train the team to use scuba gear, in case they had to dive out through areas of the cave which were completely submerged, according to local officials. ||||| BANGKOK — Rescue workers searched a large cave network in northern Thailand on Monday in the hopes of finding 12 boys and their soccer coach, who have been missing for two days. 
  
 Heavy rains have flooded a narrow passage leading into the cave complex, blocking the group’s exit and complicating rescue efforts, officials said. 
  
 The drama of the rescue attempt has dominated television news and social media in Thailand, and King Maha Vajiralongkorn Bodindradebayavarangkun was said to be following the rescue efforts. |||||
Output:
The search for a youth soccer team lost for three days in a cave in Thailand resumed Tuesday with a message of hope. "We are still optimistic they are all alive," Deputy Prime Minister Prawit Wongsuwon said, adding, "even though they may not have anything to eat, they should have water to drink." It was a message fueled by the discovery of fresh handprints and footprints inside the Tham Luang Nang Non cave complex, which the 25-year-old team coach and 12 boys aged 11 to 16 are believed to have entered Saturday through a 50-foot-long tunnel crossed by a stream. With heavy rains, that stream has now become a wall of water, partially flooding caves and passageways, some of which extend nearly 4 miles underground in Chiang Rai province, per the BBC. "Our concern is about the rain. The water inside the cave keeps rising," deputy governor Passakorn Bunyalak tells the New York Times, though officials are pumping water out. Still, officials believe the team remains alive—though perhaps with depleted oxygen—inside the cave's main chamber. "The kids are athletes, and they have skills," says Bunyalak. "They will try to survive by continuing to move." Rescuers in scuba gear can be seen mingling with medical teams at the cave entrance, while outside, family members pray around makeshift shrines as they wait for news, and more water pumps. "When I saw his bike parked inside parked at the cave, my tears were just dropping. I was desperate to find my son," an impatient father tells CNN. "We need a miracle, I want him back."
