The British embassy in Sanna has been closed until further notice, a British diplomat told Agencies on Saturday, days after a rebel attack on the US mission killed 16 people. "The embassy has closed its doors until further notice and has suspended all the services that it provides," said the source, who requested anonymity. The decision comes as the Yemeni authorities tighten security around foreign diplomatic facilities after an Al-Qaeda-linked group, the Organisation of Islamic Jihad, claimed responsibility for Wednesday's attack and threatened more.
