"They say two more ships have been hijacked, we are still trying to know where in Somalia they were seized," said Andrew Mwangura, of the Kenyan branch of the global Seafarers organisation representing the maritime industry.
Mwangura told Reuters he was informed of the possible hijacking by colleagues in Dubai where both ships had embarked on their trips.
"The ship that was laden with oil was just passing Somalia, and the other one was carrying foodstuff destined for Somalia," he told Reuters from the port of Mombasa.
Details were vague, but Mwangura said one of the ships was registered in Nicaragua. He could not say how many crew members were on board the boats.
UPDATE: 1930, 14 Oct- It may well be that the tanker is the San Carlos, reported here and the food ship doesn't exist...more to follow.
