AP Moller-Maersk has said hope is fading for four seafarers missing after a fire on the Maersk Honam 340 miles from India's Lakshadweep Islands.

Comprehensive search efforts have failed to find the crewmen following the blaze on the 15,262-teu boxship (built 2017) on Tuesday.

“While search operation continues, the hope of finding our missing colleagues is fading," said AP Moller-Maersk COO Soren Toft.
