SHANA � Iranian President Hassan Rouhani issued an order regarding mobilization of all the national forces to accelerate search operation for finding the missing crew of the stricken Iranian oil tanker.

The president issued the instruction in a meeting with Iranian Minister of Petroleum Bijan Zangeneh, Minister of Foreign Affairs Mohammad Javad Zarif and Minister of Road and Urbanization Abbas Akhundi in attendance on Tuesday.

"For the time being, the most vital issue is determining the fate of the tanker's crew and notifying their esteemed families and at the same time following up on the required legal matters regarding compensation for the incident's damage," Rouhani said.

An Iranian oil tanker carrying gas condensate collided with a Chinese ship and exploded in the East China Sea on Saturday evening.

The Sanchi tanker, heading to South Korea and registered in Panama, collided with the CF Crystal some 160 nautical miles off the coast near Shanghai.

The Iranian tanker was carrying 136,000 tonnes of condensate, an ultra light crude, an equivalent of under a million barrels worth around $60 million based on current crude oil prices.

South Korean customers had purchased the cargo on a Persian Gulf FOB basis.

NITC formed an emergency committee with senior company officials immediately after the news of the collision was transmitted to Tehran.

The state-run company has dispatched two vessels sailing in the region to the spot of the explosion to offer help to rescue operations.
