MOGADISHU: Pirates from Somalia who hijacked a Chinese bulk carrier in the Indian Ocean threatened on Tuesday to execute its 25 Chinese crew members if any rescue operation was attempted.

The De Xin Hai was carrying about 76,000 tons of coal from South Africa to India when it was seized by gunmen on Monday some 700 nautical miles east of the failed Horn of Africa state.

“We tell China not to endanger the lives of their people with any rescue operation,” Hassan, an associate of the gang, said by phone from the pirate stronghold Haradheere.

“If they try that we will execute the whole crew ... we tell them to change their mind regarding any rescue, otherwise they will regret it. We know what they are planning to do.”

Chinese Foreign Ministry spokesman Ma Zhaoxu told reporters earlier in Beijing that his government had “actively started rescue operations” for the ship.

“We will continue to follow developments closely and make all-out efforts to rescue the hijacked ship and personnel,” he said, while giving no details of China’s plans.

China sent three navy ships to the Somali coast in January to join world efforts to protect shipping in the region from pirates and has previously come to the aid of some stricken vessels.

Indian coal traders feared Monday’s incident — the first reported hijacking of a coal vessel by Somali pirates — could mean the gunmen would start targeting other coal ships as these dry bulk vessels are smaller and have a relatively small crew.

That could disrupt an expected increase in the volume of South African coal heading to India over the coming months, following a boom in Indian demand during the past two years.

The European Union’s counter-piracy force said an EU maritime patrol aircraft had located the vessel on Monday.

“The aircraft spotted at least four pirates on the deck and the vessel is towing two skiffs. It was last reported heading west towards the Somali coast,” said John Harbour, a spokesman for the EU naval force in Brussels.

Hassan said his colleagues were planning to sail the captured ship to either Haradheere or Hobyo, both former fishing villages north of Mogadishu that have become pirate bases.

A spokesman for its owner, Qingdao Ocean Shipping Co. Ltd., told China’s official Xinhua news agency that it had received a report from the ship at 3:50 p.m. Beijing time on Monday saying that armed pirates were on board, but then it lost contact.

Despite a major deployment this year by foreign navies in the strategic shipping lanes linking Europe to Asia through the Suez Canal, pirate gangs have continued to terrorize the waters off Somalia, making tens of millions of dollars in ransoms.

Last Thursday, Somali gunmen captured a Singapore-owned container ship, the MV Kota Wajar, which had 21 crew on board.
