Maritime officials say they fear another merchant ship has been hijacked in Somali waters in recent days.
Andrew Mwangura, a spokesman for the Kenyan branch of the Global Seafarers Organization, says pirates may have seized a ship transporting cargo from Dubai to Somalia. However, details about the ship, its crew and cargo are vague.
A series of hijackings off the coast of the lawless horn of Africa nation has plagued the shipping industry in recent months.
There have been at least 23 reported ship hijackings since March, including two United Nations World Food Program vessels taking food aid to Somalia. The U.N. ships were eventually released, but the agency has said it is considering alternatives to ensure the safety of its employees.
