A boat carrying around 56 people capsized off the coast of India’s financial capital of Mumbai on Wednesday, a statement from the local authority said.
A total of 21 people were rescued, of whom one was declared dead later, the Brihanmumbai Municipal Corporation said in a statement.
Rescue and relief operations were ongoing, it added. Local TV showed rescue workers in lifejackets near the capsized vessel.
Local media showed a video of a speedboat with at least five people crashing into the passenger vehicle, causing the accident.
"The speedboat crashed into our boat and water started entering our boat and it overturned. The driver asked us to wear lifejackets,” a passenger on board the vessel told ABP Majha news channel.
"I swam for 15 minutes before I was rescued by another boat,” the passenger, who did not identify himself, said.
The boat, called Neelkamal, was heading towards the Elephanta caves, a popular tourist destination off the coast of Mumbai, when it capsized, the Brihanmumbai Municipal Corporation said.
The caves, which see a steady stream of tourists through the year, are a UNESCO heritage site and were constructed in the 5th to 6th centuries A.D. Boats from the Gateway of India, Mumbai’s southernmost point, make regular trips to ferry tourists to the site, an hour away.
