He paused in kidnappings during monsoon rains, but the sea Somali gangs have increased their attacks in the past two months, especially outside the Seychelles as pirates extend its range of marine patrols to avoid war in the Horn Africa.

“The captain of the chemical tanker died last night from gunshot wounds he got during the hijack,” a pirate who gave his name as Mohamed told Reuters. “The ship is headed for Haradheere with the dead captain.”

The European Union naval force EU Navfor force operating in the area said on Tuesday that pirates had seized the 22,294 DWT tanker MV Theresa VIII 180 nautical miles northwest of the Seychelles with 28 North Korean crew on board.

The ship that is operated from Singapore had been sailing to the Kenyan port of Mombasa but had turned round after being seized near the Indian Ocean archipelago. EU Navfor said on Wednesday that pirates had also attacked the same U.S. ship they hijacked in April this year.

The European force said gunmen opened fire on the Maersk Alabama with automatic weapons on Wednesday morning, but a security detachment with the huge container ship responded and the vessel managed to escape with no casualties reported.

In April, the captain of the Maersk Alabama volunteered to board a lifeboat with pirates in return for the safety of his 19 crew members. He was held for several days aboard the lifeboat, which was closely trailed by a U.S. warship.

The tense standoff ended when U.S. Navy snipers killed three pirates. A fourth suspected gunmen was captured and taken to the United States to face trial.

Somali pirates released a Spanish tuna fishing boat on Tuesday but are still holding at least 13 vessels and more than 200 crew members hostage.
