Following increased tensions between Tehran and London over the detention of 15 British marines who entered Iranian waters illegally and likely gatherings by protestors in front of the embassy compound, the police increased security measures and arrangements around the embassy here in Tehran on Friday.

I do apologize to the Iranian people for entering Iranian waters illegally and without any permission, Thomas Summers, one of the 15 British marines who were arrested after trespassing Iran’s territorial waters said here on Friday.

Iranian President Mahmoud Ahmadinejad, in a phone conversation with Turkish Prime Minister Recep Tayyip Erdogan on Friday, stressed that Britain should apologize to Iran for having trespassed the territorial waters of Iran.
