Rescue teams work to locate survivors after New Delhi building collapse.

A multistorey building in the Indian capital, New Delhi, has collapsed, killing at least six people and trapping dozens of others.

Rescue teams are searching the rubble of the collapsed building, which housed mostly students, near a Delhi University campus in Satya Niketan on Sunday.

The All India Institute of Medical Sciences (AIIMS) said it treated several victims after the incident.

“Out of the 10 patients, five were brought dead, while one patient who was in critical condition later succumbed to his injuries,” AIIMS said in a statement.

Crews from India’s disaster response agency, police and firefighters cleared debris with earthmovers and used detection dogs to search for those trapped inside. A nearby building was evacuated over concerns that it could also collapse.

Up to 40 people remain trapped under the rubble, according to fire officer Abhilash Malik. The number of survivors and the cause of the accident were not immediately clear.

A video filmed by a man trapped under the rubble as onlookers called for rescuers to help him has circulated online. Additional footage showed residents attempting to rescue survivors before disaster response teams arrived.

“The most important thing for us is to save the lives of these students. Rescue operations will carry on,” Delhi Chief Minister Rekha Gupta told local news outlets.

“I assure you we won’t spare the guilty,” she said.

“Condolences to those who lost their loved ones. Praying for the speedy recovery of the injured. Authorities are working at the site and assisting those affected in the mishap,” Indian Prime Minister Narendra Modi’s office said on X.

Building collapses are frequent in parts of India during the rainy season from June to September. A similar incident occurred on Saturday after a three-storey building collapsed in northern India following heavy rain. No casualties were reported.

In 2025, at least 11 people were killed after a residential building collapsed in the northeastern district of New Delhi.
