Pirates in the Gulf of Aden hijacked a chemical tanker carrying a crew of 15 Bulgarianson Tuesday. The European Union Naval Force Somalia in a press release said, the Bulgarian-flagged tanker, the MV Panega, was about 100 nautical miles east of Aden, Yemen, en route from the Red Sea to India. As long as the pirates are on board the ship, we are just monitoring the situation, said Anders Kallin, a Swedish Navy Commander for the EU naval force. He said he had no reason to believe that anyone had been hurt.
