Hong Kong on Saturday mourned the 128 people known to have died in a massive fire at a high-rise apartment complex, a toll that is likely to rise with 200 others still unaccounted for days after the disaster.

Authorities have arrested 11 people in connection with the city’s worst blaze in nearly 80 years as they investigate possible corruption and the use of unsafe materials during renovations at the Wang Fuk Court complex.

Rescue operations at the site in the district of Tai Po, near the border with mainland China, concluded on Friday, though police say they may find more bodies as they search the burnt-out buildings as part of ongoing investigations.

The fire started on Wednesday afternoon and rapidly engulfed seven of the eight 32-storey blocks at the complex, which were wrapped in bamboo scaffolding and green mesh and layered with foam insulation for the renovations.

Authorities have said the fire alarms at the estate, home to more than 4 600 people, had not been working properly.

Hong Kong leader John Lee, other officials and civil servants, all dressed in black, stood in silence for three minutes early on Saturday outside the central government offices, where flags were lowered to half-mast.

Condolence books have been set up at 18 points around the former British colony for the public to pay their respects.

“Our most heartfelt thoughts are with all those who have lost loved ones and with those that are now living with shock and uncertainty,” Britain’s King Charles said in a statement about the “appalling tragedy”.

At Wang Fuk Court, police officers from the disaster victim identification unit, wearing white overalls, helmets and oxygen masks, entered one of the charred buildings to continue their search for remains.

They climbed over mounds of bamboo scaffolding that had fallen during the disaster and around large puddles of water created after firemen doused the buildings for days to try to lower the temperatures inside.

Families and mourners gathered to lay flowers while some faced the grim task of looking at photographs of the dead taken by rescue workers.

Authorities said on Friday that only 39 of the 128 dead had been identified. Hong Kong’s Lee has said the government would set up aHK$300 million ($40 million) fund to help residents while some of  China’s biggest listed companies have pledged donations.

Hundreds of volunteers have also mobilised to help the victims, sorting and distributing items from diapers to hot food.
They formed teams to collect, transport and distribute goods in round-the-clock shifts and have set up a sprawling support camp for displaced residents beside a shopping mall across from the complex.

At least two of the dead were domestic workers from Indonesia, the country’s consulate said. Dozens of domestic workers from the Philippines were also caught up in the disaster and 19 were still missing, said Edwina Antonio, executive director at Bethune House, a refuge association for migrant women.

Hong Kong has around 368000 domestic workers, mostly women from low-income Asian countries who live with their employers, often in cramped spaces.
