On Sunday, the Ministry of External Affairs (MEA) informed that an oil tanker with 22 Indian nationals onboard was presumably missing off the coast of Benin in the Gulf of Guinea.
MEA spokesperson Raveesh Kumar in a tweet had said, "A merchant vessel Marine Express (oil tanker), owned by Mumbai-based Anglo-Eastern shipping company with 22 Indian nationals onboard, is presumably missing off the coast of Benin in the Gulf of Guinea."
He informed that the Indian authorities based in Nigeria have sought the country's help in locating the missing oil tanker.
"Our Mission in Abuja (Nigeria) is in touch with the authorities in Benin and Nigeria for their help in locating the ship and is constantly monitoring the situation," he informed in another tweet, adding that a 24-hour helpline was set up for information on then missing Indians.
The owners of the tanker, which was loaded with gas oil urged the Directorate General of Shipping in Mumbai to get in touch with their counterparts in Nigeria and Benin to carry out search operations for the merchant ship.
According to initial reports, the ship vanished from West Africa amidst possibility of hijack by the pirates.
