TEHRAN, Iran (AP) _ Eight British Navy sailors serving in Iraq will be prosecuted on charges of entering Iran's territorial waters, Iran's state-run television reported Tuesday.

``They will be prosecuted for illegally entering Iranian territorial waters,'' the Arabic language Al-Alam television reported. The station is part of the state-run Iranian radio and television network.

Iran impounded the three British boats and detained the eight crewmen Monday in the Shatt-al-Arab waterway, Iraq's main link with the Persian Gulf. It said the crewmen were armed.

Britain said it was in contact with Iran to resolve the situation. It said the personnel from the Royal Navy training team based in southern Iraq had been detained while delivering a boat to the new Iraqi Riverine Patrol Service.
