Over 15 countries have called for a special meeting with the UN's shipping agency to discuss the safety of ships and their crews sailing through the Black Sea and Sea of Azov after Russia's invasion of Ukraine and growing dangers to vessels.
Many shipping firms have suspended sailings to affected Black Sea ports and other terminals in Ukraine. Insurance premiums for voyages have soared since Russia's invasion on Feb. 24, an action Moscow calls a "special operation".
An Estonian-owned cargo ship sank on Thursday off Ukraine's major Black Sea port of Odessa, hours after a Bangladeshi vessel was hit by a missile or bomb at another port. This followed at least three other ships being hit by projectiles in recent days.
