A Maltese tanker leaked oil into the Mediterranean off Egypt's north coast on Saturday because of a technical problem, an official with a governmental environment affairs agency said. "The spill happened early on Saturday," the official said. He added the tanker Good Hope had stopped leaking oil but there was a spill about 1 km (0.6 miles) square in size about 1 km from Egypt's north coast, east of the port city of Alexandria. He said local authorities were cleaning up the spill and had no plans to close ports on Egypt's Mediterranean coast.
