Somali pirates seized a Greek cargo ship and a Yemeni fishing boat in the latest attacks demonstrating their ability to evade international naval forces, Reuters quoted gunmen and officials as saying today. Patrols by a multinational naval force in the strategic shipping lanes that link Europe to Asia through the busy Gulf of Aden only appear to have forced the sea gangs to extend their range and strike deeper into the Indian Ocean. One of the pirates, Hassan, told Reuters by telephone from the coastal town of Haradheere that three of his comrades were wounded while seizing the bulk carrier late on Tuesday. "There was brief fighting before we captured it. Three of my friends were injured," he said, adding that its crew were safe. Pirates from the failed Horn of Africa state are holding at least 13 vessels and more than 230 crew hostage, including a British couple whose yacht was hijacked off the Seychelles. Spain"s Defence Minister on Wednesday called for international cooperation to trace ransoms paid to the pirates, which she said were channelled through British-based law firms. "The international community has to cut the source of funding, which gets to the pirates via payments made by European law firms," Carme Chacon told Spanish National Radio, singling out "certain British law firms". Spain is trying to secure the release of fishing boat Alakrana, whose home port is in the Basque Country, which was seized on Oct. 2 with 36 crew on board. Andrew Mwangura of the Kenya-based East African Seafarers" Assistance Programme named the Greek cargo ship taken on Tuesday as the 150 m (492 ft) Marshall Islands-flagged MV Filitsa. He said it had three Greek officers and 19 Filipino sailors aboard and was carrying bulk urea from Kuwait to South Africa. The European Union naval force EU Navfor said the 23,709 tonne Filitsa had been hijacked in the south Somali Basin, some 400 nautical miles northeast of the Seychelles; around 1,000 nautical miles east of the Somali capital Mogadishu. The distance roughly equals the longest range Somali pirate attack to date; an attempt to seize a Hong Kong-flagged crude oil tanker on Monday. That bid failed, but it was a stark demonstration of the pirates" ambition to outwit the modern navies deployed against them and defeat more determined defences by their civilian prey. NATO and the EU play a lead role against pirates in the region, but navy ships from China, Russia, Japan and other nations are also involved in the operation that is stretched thin in the vast Indian Ocean.
