What are your thoughts?Fifteen Royal Navy sailors have been seized by Iranian warships in Iraqi territorial waters, the Ministry of Defence says.
Foreign Secretary Margaret Beckett has summoned the Iranian ambassador in London to demand their immediate release, a spokesman said.
The incident happened following a a routine inspection of a merchant ship off Iraq.
The MoD said: "The boarding party had completed a successful inspection of a merchant ship when they and their two boats were surrounded and escorted by Iranian vessels into Iranian territorial waters.
"We are urgently pursuing this matter with the Iranian authorities at the highest level and on the instructions of the Foreign Secretary, the Iranian ambassador has been summoned to the Foreign Office.
"The British Government is demanding the immediate and safe return of our people and equipment.''
The personnel seized were from the Type 22 frigate HMS Cornwall.
A BBC News 24 reporter on the ship, Ian Pannell, said that they had just boarded a dhow.
"While they were on board, a number of Iranian boats approached the waters in which they were operating - the Royal Navy are insistent that they were operating in Iraqi waters and not Iranian waters - and essentially captured the Royal Navy and Royal Marine personnel at gunpoint,'' he said.
I think if they knew the ships were british, they should have stayed away instead of just causing problems.
