Press TV - An Iranian-flagged ship has drowned off Azerbaijan's eastern coast in the Caspian Sea, according to reports in the Azerbaijani media and local officials in Iran.

Azerbaijan's State Maritime Agency said on Friday that nine members of the crew of the ship had been rescued before it began sinking near the port in the city of Lankaran.

�Two aircraft of the Ministry of Emergency Situations and a patrol vessel of the State Border Service have been sent to the site of the accident,� said the statement.

Ali Khedmatgozar told the IRIB News that the ship was privately owned and staffed by seven Iranian�and two Indian sailors when it began drowning. He added that all members of the crew had been rescued by the Azerbaijani authorities.

The official would not definitively say what had caused�the incident but hinted that the ship had been fighting waves of up to three meters before sinking.

The world�s largest inland body of water, the Caspian Sea is surrounded by Iran, Azerbaijan, Russia, Kazakhstan and Turkmenistan.
