Egypt migrant boat capsize: Hundreds feared dead
Survivors from a boat which capsized off the Egyptian coast on Wednesday have told the BBC that hundreds of people may have drowned.
The boat was carrying between 450 and 600 migrants when it capsized eight miles (12km) off the coast, they say. The numbers have not been confirmed.
Authorities say they have rescued 163 people and recovered 51 bodies so far off the port city of Rosetta.
Four crew members have been arrested, Egyptian officials said. They are suspected of involuntary manslaughter and human trafficking, judicial officials were reported as saying.
The incident came after the EU's border agency warned that increasing numbers of Europe-bound migrants are using Egypt as a departure point.
The UN says that more than 10,000 people have died crossing the Mediterranean towards Europe since 2014.
The boat was kept off the coast for five days as more and more migrants were brought on board, survivors told the BBC's Orla Guerin in Rosetta.
The boat is said to have capsized after a final group of some 150 people were crammed on board.
