Iran has demanded an apology from the UK Government over the arrest of its former ambassador to Buenos Aires on terrorism charges. President Mohammad Khatami escalated the diplomatic row with Argentina and the UK in remarks on Iranian state radio. "I hope that the British Government will swiftly go back on this incorrect action and apologise," he said. The former ambassador, Hadi Soleimanpour, was arrested by British police on Thursday in Durham, northeast England, over his alleged role in the bombing of a Jewish community centre in Buenos Aires in 1994 in which 85 people died.
