Iran said Monday it was questioning 15 British sailors and marines to determine if their alleged entry into Iranian waters was "intentional or unintentional" before deciding what to do with them.

The 14 men and one woman were captured at gunpoint on Friday after searching a civilian cargo vessel in the Shatt al-Arab, the thin waterway in the Persian Gulf that marks the border between Iran and Iraq.

Iran maintains the sailors and marines crossed over into Iranian waters while Britain insists they stayed in Iraqi territory. Iran has refused to say where the captured personnel were being held or to allow British officials to speak with them. Calls for the British soldiers release came from the European Union, Iraq and the United States, under whose command they were serving when they were seized.
