Egyptian security and hospital officials say 11 fishermen have drowned and 11 were injured after their boat collided with another passing ship near the country's southern Sinai.

The officials said there were 45 fishermen on the boat and 23 of them are still missing after Sunday's collision in the Gulf of Suez. Egyptian naval forces and other security and medical teams hurried to the shores of the town of Al-Tur, the capital of southern Sinai, to aid the fishermen. Officials say three boats in the area were helping to search for those missing.

The officials spoke on condition of anonymity because they are not authorized to brief journalists.
