The death toll in the building collapse in Mumbai, India, has increased to five and at least eight people, including children and senior citizens, are still trapped under the debris, NDTV, an Indian television channel reported.

The residential building called the Altaf Manzil, located in central Mumbai, collapsed on Monday night after heavy rains lashed the city. Rescue operations are still on with help from more than 60 fire brigade personnel and the National Disaster Response Force team, or NDRF, according to IBNLive.

"There are no problems as of now. Everyone is doing their duty. Our entire NDRF team is at work. About 90 members are in action and we have been working through the night. Local authorities are also helping us," an NDRF official told IBNLive.

On Monday, it was reported that at least 20 people were believed to be trapped when the four-story building caved in. The injured have been admitted to nearby hospitals.

"The fire brigade, police and personnel of disaster management immediately came to the spot,” Sakil Ahmed, a resident told ANI. “Rescue and relief operation has been going on throughout the night. Survivors have been taken to the hospital."

Several vehicles, including cars that were parked on Cadell Road near the Altaf building, were crushed by the debris as well.
