By Michael Holden and Ahmed Aboulenein LONDON (Reuters) - British Prime Minister David Cameron vowed on Friday to use all means at his disposal to hunt down militants such as "Jihadi John" after the killer was unmasked as a Kuwaiti-born computer programming graduate from London. The black-clad militant brandishing a knife and speaking with an English accent was shown in videos released by Islamic State (IS) apparently decapitating hostages including Americans, Britons and Syrians. "When there are people anywhere in the world who commit appalling and heinous crimes against British citizens, we will do everything we can with the police, with the security services, with all that we have at our disposal to find these people and put them out of action," Cameron said. Cameron refused to go into the unmasking of "Jihadi John" as 26-year-old British militant Mohammed Emwazi, but said that people should get behind the security services, which he praised as impressive and dedicated to defending Britain.
Los Angeles (AFP) - Actor Leonard Nimoy, who won a worldwide fan base as the pointy-eared half-human, half-Vulcan Mr Spock in the blockbuster "Star Trek" television and film franchise, died Friday at age 83, US media reported.
By David Adams and Arshad Mohammed WASHINGTON (Reuters) - Cuban and U.S. officials held talks on Friday aimed at restoring diplomatic relations, with Cuba pushing to be removed from a U.S. list of state sponsors of terrorism but Washington saying the designation should not be linked to the negotiations on opening embassies. Washington severed diplomatic relations with Cuba 54 years ago. The delegations at Friday's talks, which followed a first round of negotiations in Havana last month, were headed by Roberta Jacobson, U.S. assistant secretary of state, and Josefina Vidal, chief of the Cuban foreign ministry's U.S. division. The United States said the talks should focus on issues around the functioning of diplomats in future embassies, but Communist-run Cuba is pressing Washington to remove it from its terrorism list before the official restoration of diplomatic ties.
