Arab foreign ministers will gather for an emergency meeting to discuss a common response to the Israeli offensive in the Gaza Strip that has killed more than 50 people in the past week, the Arab League Secretary-General said Thursday. Secretary General Amr Moussa said he called for the meeting on Sunday In Cairo at the request of Palestinian and Lebanese officials to "look into practical steps and measures to deal with the Israeli ongoing and recurrent aggression on the Palestinian people, latest of which is the Beit Hanun massacre." Palestinian Foreign Minister Mahmoud Zahar of Hamas also came to Cairo on Thursday to discuss "the latest tragic incidents in Gaza" with his Egyptian counterpart. Egyptian Foreign Minister Ahmed Aboul Gheit condemned the ongoing Israeli offensive in the Palestinian territories, a statement issued by his office said. In New York, meanwhile, the UN Security Council scheduled an open meeting on Thursday in response to Palestinian calls for it to condemn Israel's killing and demand the withdrawal of Israeli troops from the Gaza Strip.
