The death toll from the devastating flash flood has reached 1,287, authorities said Friday, as rescue teams continued searching for missing people and assessing extensive damage to homes, roads and other infrastructure.

The National Disaster Risk Reduction and Management Authority, under the Ministry of Home Affairs, said 1,287 bodies, including human remains, had been recovered across eight districts affected by the disaster as of 12:30pm.

The toll includes 140 bodies recovered in Rasuwa, 184 in Nuwakot, 63 in Dhading, 72 in Gorkha, 38 in Tanahun, 219 in Nawalparasi East, 212 in Nawalparasi West and 359 in Chitwan.

Authorities said 96 bodies had been identified and handed over to relatives. More than 5,300 people have received medical treatment for injuries.

Rasuwa and Nuwakot have been among the worst-affected areas, with thousands of people still unaccounted for, according to district authorities.

Authorities said about 5,083 people remained unaccounted for, although the figure includes unidentified bodies recovered by search teams and therefore does not represent a confirmed number of people still missing.

District authorities in Rasuwa and Nuwakot reported about 2,130 and 2,340 missing people, respectively. The official tally also lists 583 foreign nationals as missing.

The National Disaster Risk Reduction and Management Authority said the figures are being continuously updated as authorities identify recovered bodies and verify reports involving tourists, foreign nationals and Nepali residents travelling with foreign visitors.

Rescue teams have so far brought 13,013 people to safety, according to the disaster authority. The Nepali Army, Nepal Police and Armed Police Force have been involved in air and ground operations, with the army conducting hundreds of flights to evacuate people from affected areas.

Two workers trapped for days inside a tunnel at the Trishuli 3A Hydropower Project were also rescued alive Friday, offering a rare breakthrough as search teams continued looking for survivors.

More than 21,000 security personnel have been deployed for rescue, relief and recovery operations, including nearly 9,300 army personnel, 7,900 police officers and more than 4,200 members of the Armed Police Force.

The disaster has caused widespread destruction to private homes and public infrastructure. Authorities estimate that 7,570 private houses have been destroyed. At least 48 government buildings, 18 schools and seven health facilities have also been damaged or destroyed.

About 55 kilometres of roads have been completely damaged, while 33 motorable bridges and 68 suspension bridges have been destroyed, according to the authority.

Relief supplies have been sent by road and air to affected districts, while telecommunications services have gradually been restored. Nepal Telecom said 116 of 120 affected towers were back online, while 75 of 78 Ncell towers had been restored.

The government has also released emergency funds to Rasuwa, Nuwakot, Dhading and other affected local governments to support immediate relief and recovery.
