(BBC) – More than 90 people are missing after a barge off the coast of the Indian city of Mumbai sank amid a severe cyclone.
The Indian navy said it had rescued 177 of the 270 people aboard and that efforts to find survivors were ongoing.
Three other commercial barges carrying about 700 people are stranded at sea in the wake of cyclone Tauktae, which has battered India’s western coast.
Tauktae weakened after it made landfall on Monday, but at least 19 people have already died in the storm.
The stricken barge, owned by India’s Oil and Natural Gas Corporation (ONGC), was carrying personnel deployed for offshore drilling. When the storm struck, the barge’s anchors gave way and it began drifting.
The Indian navy has mounted a massive air and sea rescue mission for the missing oil workers, which is being hampered by huge waves: “There are waves of 20 to 25 feet (six to 7.6m), the winds are high and the visibility is low,” said navy spokesman Vivek Madhwal.
“Ships and aircraft have been deployed for the search and rescue mission.”
A navy spokesman told the BBC it had dispatched three warships to save those aboard the three stranded commercial barges. Two of the barges are off the coast of Mumbai, the capital of Maharashtra state, while the third is off the coast of Gujarat.
