Seized sailors are 'fit and well'
The 15 Royal Navy personnel who were seized four days ago are fit and well, Iran has told the Foreign Office.
A senior Iranian official told the UK's ambassador in Tehran that the Britons were being held in Iran but would not disclose their exact location.
He said Iran was "working to resolve the matter as soon as possible".
Iran says the Britons could be charged with illegally entering Iranian waters, although both Iraq and the UK insist they were in an Iraqi area.
Escalation
British ambassador Geoffrey Adams was assured that the eight sailors and seven marines were well during an hour-long meeting on Monday with Ebrahim Rahimpour, a senior official at the Iranian foreign ministry in Tehran.

Mr Rahimpour agreed to stay in close touch with the British embassy but declined to say what plans Iran had for their release, according to a statement from the Foreign Office.
The Iranian state news agency IRNA said Mr Rahimpour told Mr Adams that the 14 men and one woman could face legal proceedings.
