A large cargo ship carrying more than 14,000 sheep overturned off the coast of Romania.
The Queen Hind capsized on Sunday morning after leaving the port of Midia, near the south-eastern city of Constanța, on the Black Sea coastline.
All crew members i.e 22 Syrian nationals were rescued.
An operation, involving police, firefighters and the Romanian Navy to save the sheep was launched.
Some sheep found swimming near the Palau-flagged ship have been rescued so far but many are believed to have drowned.
Meanwhile, one crew member was taken to hospital with hypothermia.
It is not yet known what caused the ship to capsize. An investigation will be carried out when the operation to rescue the sheep and salvage the vessel is finished, authorities said.
