Indian Prime Minister Narendra Modi has described the collapse of a student hostel in south-west Delhi as "distressing", as emergency crews pulled a ninth survivor from the wreckage.

In an official statement offering condolences to those who lost loved ones, Mr Modi joined local officials in monitoring the response in the Satya Niketan neighbourhood, where a five-storey residential building collapsed on Sunday shortly after midday.

We previously reported that eight people had been rescued and three were in a critical condition. Local newspaper The Hindu reports that nine people have now been brought out alive from the debris, with five of them taken to hospital in a critical condition. Three people are confirmed to have died, and dozens more remain feared trapped.

The property, known as Hostel Daze, was situated near the Delhi University campus and housed paying student residents. Eyewitnesses estimated that up to 50 people were inside when the structure gave way at around 13:30 local time (08:00 GMT), with many students in their rooms owing to the Sunday break from classes.

Rescue workers continue to search through concrete slabs and brickwork. Indian television broadcasts showed one young man being pulled clear while another remained pinned beneath a fallen metal slab. A local legislative assembly member at the scene confirmed earlier that several trapped students had managed to place phone calls from beneath the rubble.

Chief Minister of Delhi Rekha Gupta said that "every possible effort is being made to safely rescue those trapped" and confirmed an adjacent building was evacuated as a precaution. While some eyewitnesses suggested a neighbouring property had also collapsed, this has not been officially confirmed.

Investigators remain focused on unapproved structural alterations. While Delhi Police stated the building was between 40 and 50 years old, a neighbouring shopkeeper told news agency ANI that the property was held under a 100-year lease and that excavation was taking place in the basement to increase room capacity.

"They strengthened the upper building, but the pillars below were weak," the shopkeeper said, noting that labourers working on the excavation were among those buried. Police are searching for the owner of the building, according to the Times of India.

The National Students' Union of India has demanded a formal inquiry into the incident, warning that "negligence with the safety of students and common people will not be tolerated at any cost."

Building collapses remain a regular hazard in India's major cities, where substandard materials, weak foundations and unpermitted works are widespread. Delhi fire department figures show more than 1,000 structural collapses have occurred across the capital over the past three years, including an incident last April in north-eastern Delhi that killed 11 people.

What we still do not know is the precise number of people who remain unaccounted for, or whether local authorities had granted permits for the basement work. I will continue to update this report as further details emerge from the site.
