Rescuers worked under floodlights in humid summer conditions to remove portions of a wall with a crane as a crowd stood by, anxious for updates.
On Friday morning local time, thermal imaging showed body heat in the rubble, while another device picked up seven breaths, according to a member of Live Love Beirut, a non-governmental organization helping with rescue efforts. The group said rescuers were less than 2 meters (6.5 feet) from that location.
Rescuers asked a crowd of about 200 onlookers to be silent so their equipment could better detect any breath or heartbeats of a possible survivor .
The search was sparked by a rescue dog that passed the destroyed building with a Chilean rescue team on Thursday and indicated signs of life, said Eddy Bitar, a local non-governmental organization worker.
Thermal imaging later showed two bodies — one small body curled up next to a larger body. A listening device also registered a respiratory cycle of 18 per minute, Bitar said.
“There’s a small chance that the person is still alive,” Bitar said.
Rescue teams are digging tunnels through thick concrete debris to reach the site of the potential survivor. Francisco Lermanda, a worker with Chilean search and rescue NGO Topos Chile, was cautious about the prospect of finding someone alive after so many days beneath the rubble. But he didn’t rule it out.
One person survived 28 days under rubble in Haiti, he added.
Tension at the site
Thursday’s search was temporarily suspended over concerns that a wall could collapse and endanger the lives of the rescue team, Beirut fire brigade officer Lieutenant Michel El-Mur said. After the search was suspended on Thursday night, local time, a protest of around 100 people erupted outside the site.
“That breath is our last breath. It’s our last hope. You should all be ashamed,” yelled protester Melissa Atallah. One woman was heard saying: “We have been here for a month, can’t you stay up for one night?”
Scores poured into the site of the rescue effort after the Chilean team had left, demanding the immediate resumption of the operation. One woman said she ordered a crane, while other protesters climbed up the wreckage offering to search for the body themselves.
Tension continued to grow until soldiers told the protesters that the team and its equipment would be returning to the site imminently.
Multiple people CNN spoke to said a strong, putrid smell emanated from the destroyed building in the aftermath of the blast. One woman said she repeatedly alerted authorities about it and urged them to search the site.
“Two weeks ago we were protesting here and we smelled what felt like ‘old blood’,” said Reine Abbas. “If they had checked back then, then the body would probably be alive today.”
“But this is Lebanon.”
“There is no time for talk, promises and wishes. It is a time for action,” Adib said in a short acceptance speech.
