TEHRAN, Jan. 15 (Xinhua) -- Iran's military destroyer Damavand crashed into wave breakers at a port in the Caspian Sea and two of its crew members are missing, Tasnim news agency reported on Monday.

A search operation is underway to find the two servicemen missing in the accident that happened on January 10, the report quoted army spokesperson General Shahin Taqikhani as saying.

Strong winds and a sea storm led to the crash, said Taqikhani.

Contrary to the initial reports about minor damages to the destroyer, the assessment teams have found out that the vessel has suffered serious damages and needs a complete overhaul, he said.

On Wednesday, Damavand destroyer crashed into wave breakers when it was docking at port in Iran's northern province of Gilan in stormy weather.

The 100-meter-long destroyer that weighs more than 1,300 tons officially joined the Navy's northern fleet in the Caspian Sea in March 2015.
