Fire officials in Hong Kong said they expected to wrap up search and rescue operations in a few hours after firefighters mostly contained the blaze at a highrise apartment complex that left at least 94 dead.
More than 70 people were injured, including 11 firefighters, along with the 94 dead, according to Hong Kong's Fire Services Department, making it one of the deadliest blazes in the city's modern history.
Rescuers holding flashlights were going from apartment to apartment at the charred towers, as thick smoke continued to pour out from some windows at the Wang Fuk Court complex, a dense cluster of buildings housing thousands of people in Tai Po district, a northern suburb near Hong Kong's border with the mainland.
Officials said firefighters were still working on a handful of apartments and trying to enter all of the units in the seven towers to ensure there were no further casualties. Authorities said they expected the blaze to be fully extinguished in the coming hours.
"Our firefighting operation is almost complete," said Derek Armstrong Chan, deputy director of the Fire Services Department. Firefighters were working hard "to prevent the debris and embers from flaring up. What's next is the search-and-rescue operation," he added.
It was unclear how many people were missing or trapped. Hong Kong Leader John Lee said contact had been lost with 279 people early Thursday. Authorities did not provide updates on the missing people or how many were still inside the ravaged buildings during a later news conference.
Video showed rescuers searching in some apartments in the dark. Orange flames were still seen from inside several windows, though the whole complex was now largely a blackened ruin.
WATCH | Deadly inferno burned through the night:A fire spread through a dense highrise apartment complex in Hong Kong has left dozens dead and hundreds more reported missing. Three construction company executives were charged with manslaughter, but the cause of the fire remains unclear.Firefighters have been trying to control the flames since midafternoon Wednesday, when the fire was believed to have started in bamboo scaffolding and construction netting, and then spread across seven of the complex's eight buildings. Fires in four buildings had been effectively put out, with the remaining three towers under control, authorities said Thursday afternoon.
Rescuers are "battling high temperatures and carefully going up floor by floor, thoroughly searching and aiming to rescue people as quickly as possible," said Wong Ka-wing, deputy director of fire services. "[We] don't rule out rescuing more injured people."
One firefighter was among the dead, authorities said. About 900 people were evacuated to temporary shelters overnight.
Corridor filled with smokeResident Lawrence Lee was waiting for news about his wife, who was still trapped in their apartment.
"When the fire started, I told her on the phone to escape. But once she left the flat, the corridor and stairs were all filled with smoke and it was all dark, so she had no choice but to go back to the flat," he said, as he waited in one of the shelters overnight.

Although they were safe, they were worried about their home.
"I couldn't sleep the entire night," Winter Chung, 75, told The Associated Press on Thursday.
Three men, the directors and an engineering consultant of a construction company, were arrested on suspicion of manslaughter. Police have not directly named the company where they work.
"We have reason to believe that those in charge of the construction company were grossly negligent," said Eileen Chung, a senior superintendent of police.
Police on Thursday also searched the office of Prestige Construction & Engineering Company, which The Associated Press confirmed was in charge of renovations in the tower complex. Police seized boxes of documents as evidence, according to local media. Phones for Prestige rang unanswered.
Authorities suspected some materials on the exterior walls of the highrise buildings did not meet fire resistance standards, allowing the unusually fast spread of the fire.
Police also said they found Styrofoam — which is highly flammable — attached to the windows on each floor near the elevator lobby of the one unaffected tower. It was believed to have been installed by the construction company but the purpose was not clear. Secretary for Security Chris Tang said they would investigate the materials further.
The fire started on the external scaffolding of a 32-storey tower, then spread on the bamboo scaffolding and construction netting to the inside of the building and then to the other buildings, likely aided by windy conditions. Firefighters aimed water at the intense flames from high on ladder trucks, but conditions for fighting the fire and rescuing people remained challenging.
A fire safety expert said the incident is "quite shocking," as regulations in general require buildings to be spaced apart to keep fires from spreading from one building to the next.
"Typically, they don't spread beyond the building of origin," said Alex Webb, a fire safety engineer at CSIRO Infrastructure Technologies in Australia, saying the materials police cited could explain why the fires spread.

The housing complex consisted of eight buildings with almost 2,000 apartments for about 4,800 residents, including many older people. It was built in the 1980s and had been undergoing a major renovation.
Chinese President Xi Jinping expressed condolences to the firefighter who died and extended sympathies to the families of the victims, according to state broadcaster CCTV. He also urged efforts to minimize casualties and losses.
The fire was the deadliest in Hong Kong in decades. In November 1996, 41 people died in a commercial building in Kowloon in a fire that lasted for around 20 hours.
