Just under 500 seafarers remain stuck onboard 109 ships at Ukrainian ports - skeleton crews who were left on board to enable their crew mates to be evacuated amid the conflict with Russia, shipping officials said on Friday.
Those remaining should be allowed safe passage out too, the International Chamber of Shipping (ICS) association said.
Two seafarers have been killed and six merchant vessels have been hit by projectiles - which sank two of them - around Ukraine's coast since the start of Russia's invasion on Feb. 24.
