International pressure is increasing on Iran to release 15 British Navy personnel seized Friday in a disputed waterway between Iraq and Iran.
British officials say they again asked Iran to free the 14 men and one woman Sunday. The European Union has also demanded they be released immediately.
Britain's ambassador to Iran met with officials at the Iranian Foreign Ministry Sunday. But British officials say they still have not been able to see the detainees or been told where they are being held.
Iran says the British detainees confessed to illegally entering Iranian waters. Iranian military officials say they are in good health and are in Tehran.
Iran's navy detained the crew Friday after the British conducted a routine inspection of a merchant ship in the Shatt al-Arab waterway between Iran and Iraq.
Three years ago, Iranian forces seized six British marines and two sailors in the same area. They were released three days later.
