SANAA, (Reuters) – Six sailors died when their vessel, owned by a United Arab Emirates company, sank off the coast of Yemen, state news agency Saba reported on Thursday.

Rescue services saved 13 sailors and retrieved the bodies of the six victims after the ship went down on Wednesday amid high waves and strong winds about 600 miles from the Yemeni port of Aden.

The vessel, carrying 5,000 tonnes of cement, was headed to the port of Zanzibar in Tanzania. Saba did not give the sailors’ nationalities.
