A British warship on a drugs patrol in the Caribbean seized two tons of cocaine with a street value of some 200 million pounds (US$360 million; ¤300 million), the government said Monday, according to AP. In a joint operation with the U.S. Coast Guard, the frigate HMS Cumberland intercepted a small speedboat in international waters some 160 kilometers (100 miles) off the coast of Nicaragua on Saturday, the Ministry of Defense said. A Lynx helicopter from Cumberland's support ship RFA Wave Knight tracked the speedboat and fired non-lethal disabling shots to stop its engines. A team from Cumberland boarded the vessel, discovered the cocaine and arrested the crew of four, the ministry said in a statement. The Cumberland, a 148-meter (488-foot), 4,000-ton ship with a crew of 250, was on a four-month patrol in the Caribbean to provide humanitarian relief and take part in anti-narcotics operations.
