Dozens of Gazans are suspected to be among 500 migrants feared dead in a shipwreck in the Mediterranean last week, a Palestinian official said on Tuesday. The vessel, which set off from Egypt on September 6 bound for Europe, sank on Wednesday in what two Palestinian survivors said was a deliberate wrecking by people traffickers. "We have information that 15 (Palestinians) drowned and dozens more are missing after trying to emigrate to Italy," said Fayez Abu Eita, a Gaza spokesman for president Mahmud Abbas's Fatah party. "The severe living and humanitarian conditions of the Palestinians are forcing people to emigrate," Abu Eita told AFP.
