The fifth bomb attack in Turkey in a week has claimed the lives of at least two people, including a police officer. The device exploded in a rubbish bin in a cafe in the south-eastern province of Van, near the border with Iran. The tea garden is apparently popular with civil servants. There has been no claim of responsibility but a Kurdish separatist group, the Kurdistan Liberation Hawks, said it planted last week’s bombs, which targeted holiday resorts and Istanbul. Three people died after an explosion in a busy shopping centre in Antalya last Monday.
