Turkey's transportation minister says that the Togo-flagged freighter involved in the collision with a Russian navy vessel has sustained very minor damage and is able to continue sailing.

Ahmet Arslan also told Turkey's A Haber news channel that the collision in the Black Sea off Istanbul occurred in heavy fog. But he added that the exact cause is being investigated.

Arslan said: "There is only a slight damage on the freighter ship... It's on the bow of the vessel but nothing to prevent it from navigating."

Turkey's private NTV television said the vessel was taking sheep from Romania to Jordan.
