At least 10 people have been killed and many remain trapped after a four-storey building collapsed in the Indian city of Mumbai, officials say.
The cause of the collapse in the Dongri area of southern Mumbai is not clear.
Reports say the building was up to 100 years old. Recent monsoon flooding may also have been a factor.
It’s estimated disasters such as this kill about 2,000 people a year in India. Poor construction standards and dilapidated buildings are often blamed.
Rescue teams from the fire department and the national disaster response force are looking for those who remain trapped by the debris.
Some 15 families are believed to have been living in the building, police said. Ten people have been declared dead, including three children. Eight others have been admitted to hospital.
Local news reports showed images of people forming a human chain to remove debris with their bare hands.
“We heard a loud noise. Everybody shouted, ‘building is falling, building is falling’. I ran. It felt like a big earthquake,” a witness to the collapse told the NDTV news channel.
Prime Minister Narendra Modi has offered his condolences to the families of the dead.
Dozens of buildings have collapsed in Mumbai and other parts of India in recent years, often during the monsoon season between June and September.
Rescuers navigate tiny lanes

The roads leading to Tandel street, where the Kesarbai building stood, are buzzing with sirens from ambulances and fire trucks.
Police have barricaded much of the way, allowing only rescuers and hospital staff to pass through. It’s a crowded neighbourhood that is full of tiny lanes. Tandel street itself is so narrow that only one person can walk through it comfortably at a time.
So, locals have formed a human chain that stretches through the narrow lane and into the wider main street to pass through any materials necessary for the rescue. Ambulances and fire trucks have been forced to park some distance away as the lane is too narrow for them to enter. The monsoon rains, which have brought Mumbai to a standstill in recent weeks, have fortunately let up.
Cries of fear and concerned voices can be heard all around as people await news of their friends or relatives. Local residents are watching the rescue from their balconies; they appear both worried about their neighbours and scared for themselves.
In August 2017, three different buildings collapsed in Mumbai.
The city witnessed one of its worst accidents in 2013 when a building still under construction collapsed in the Thane neighbourhood, killing more than 70 people.
