MEA confirms details of the missing ship
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.
According to Maritime Bulletin, the Marine Express went missing from the same area where another tanker, the MT Barrett, had been hijacked on January 9.
The crew and the vessel were released after a week, reportedly after the owners Union Maritime paid ransom.
The owners and other stakeholders often don't disclose details of such incidents to ensure the crew's safety.
Call on this number for any information on missing crew
Raveesh Kumar, the official MEA spokesperson, has urged people to call on the 24-hour helpline set up by the Indian Embassy in Nigeria to provide any information on those missing. The Embassy can be contacted at +234-9070343860.
