UN calls for urgent action to prevent further tragedies as police believe up to 500 people remain missing

Greek authorities have rejected claims that a fishing boat that sank in the Mediterranean this week with the loss of potentially hundreds of lives capsized after the coastguard attempted to tow it, as the UN called for urgent action to prevent further tragedies.

Authorities have confirmed 78 deaths and said 104 survivors – mostly from Syria, Egypt and Pakistan – had been brought ashore, but police believe as many as 500 are missing. Witnesses have reported that up to 100 children were in the ship’s hold.

Hope dies last and for Kassem Abo Zeed it was running out fast. Hope was the force that had led him to board a plane from Hamburg and fly to Greece after he heard that a boat carrying his wife had capsized off the country’s southern coast.

But by 2pm on Thursday, 36 hours after the blue fishing trawler packed with migrants and refugees had sunk in one of the worst maritime disasters in recent Greek history, hope was fading in a way he had prayed would never happen.
