Iranian students attack British Embassy

Shouting "Death to Britain" and carrying banners with a call to "finally wipe Israel from the face of the Earth," hard-line Islamist students attempted to scale the embassy walls and pull down the flag, but were rebuffed by police.

Hours later, two new purported confessions were broadcast on Iranian state television, which aired previously unseen footage of two of the captured sailors allegedly admitting incursions into Iranian state waters.

Dressed in military uniform and looking physically healthy and relaxed, the two men stood in front of a large nautical map of the Persian Gulf, speaking as they used a pointer to indicate locations. One smiled as he spoke.

The announcer said the pair confessed to illegally trespassing Iranian waters about 10 a.m. local time on March 23.

British officials have protested the airing of such footage, contending it violates international conventions for the treatment of prisoners.

"It is completely unacceptable for these pictures to be shown on television, given the potential to cause distress to their families," the Foreign Office said in a statement Sunday.

The embassy protest came as British and Iranian officials carried on behind-the-scenes diplomatic contacts over the weekend aimed at defusing the standoff that began when the Britons were taken in disputed waters south of the Shatt al Arab waterway.

Iran was said to be studying a British diplomatic note sent in response to its own, which reportedly has suggested that Britain provide a guarantee that it will not commit any future incursions into Iranian waters. Britain has refused to apologize, insisting its service members were operating in Iraqi waters.

"We are anxious that this matter be resolved as quickly as possible, and we are bending every single effort to do that," Defense Minister Des Browne told the British Broadcasting Corp. on Sunday.

But Iran's Foreign Ministry spokesman, Mohammed Ali Hosseini, said Iran "has defended its sovereignty and territorial integrity" with the arrest of the 15 Britons and said a statement criticizing the arrest by the European Union this week was unnecessary.

"I regret to say that the European Union has supported the violation of international law by Britain," Hosseini told state television, adding that such bilateral issues can be resolved "easily, fundamentally and rationally" without outside intervention.

Iranian President Mahmoud Ahmadinejad did not refer directly to the detained British service members but predicted in an address in the city of Khorramshahr in southwestern Iran that "arrogant powers" will vanish like "bubbles on water."
