At least 22 labourers were killed on Wednesday when the railway bridge they were building across a ravine in India’s remote northeast collapsed, with four others feared dead.
The incident took place in Sairang, a town around 20 kilometres (12 miles) northwest of Mizoram state capital Aizawl — an outlying pocket of the country near the border with Myanmar.
Video footage shared by Mizoram chief minister Zoramthanga showed a metal frame that had toppled off towering columns into a wooded valley below.
“Deeply saddened and affected by this tragedy,” he wrote on X, formerly known as Twitter.
Zoramthanga, who uses one name, added that he was grateful that people had “come out in large numbers to help with rescue operations”.
Forty labourers had been working at the site, according to the Northeast Frontier Railway.
An employee of the agency, who requested anonymity as he was not authorised to talk to the media, said 22 bodies had been recovered from the wreckage.
Another four people were still missing, he added.

A committee has been set up to investigate the cause of the accident.
“Rescue operations are underway and all possible assistance is being given to those affected,” the office of Prime Minister Narendra Modi said.
Modi was “pained” by the accident and offered his “condolences to those who have lost their loved ones”, his office added.
The government will pay around $2,400 to the next of kin of those killed, it said.
Railways Minister Ashwini Vaishnaw also announced separate compensation for those killed or injured in the accident.
