Iran has threatened “serious measures” against five British yachtsmen who were seized by the Iranian navy in the Persian Gulf six days ago. Their racing boat had lost its propeller and may have strayed into Iranian waters. “Naturally, our measures will be hard and serious if we find out they had evil intentions,” an aide to Iranian president Mahmoud Ahmadinejad told an Iranian press agency. In 2007, fifteen British sailors and Marines were seized by Iran’s Revolutionary Guards in internationally disputed waters. They were held captive and paraded on Iranian television for two weeks before a smiling President Ahmadinejad released them and gave them new suits and bags of presents
