The Indian government says a Pakistani fishing boat laden with explosives bound for India blew up, killing all four people on board.
India's Foreign Ministry said in a statement on January 2 that the boat exploded after the Indian Coast Guard tried to stop and search it late on January 1.
It was not possible to independently verify India’s account.
Pakistan's Foreign Ministry said it was unclear whether the incident had happened at all.
Indian intelligence said the crew was planning "an illicit transaction" when the boat was intercepted in the Arabian Sea, around 365 kilometers off India's western coast.
India put security agencies on high alert for a militant strike last month in the lead-up to a visit by U.S. President Barack Obama at the end of January.
