UN Secretary-General Kofi Annan on Sunday repeated his call for an immediate halt to violence between Israel and Hizbullah, condemning an IAF air strike that killed at least 54 people and telling the UN Security Council he was "deeply disturbed" that his previous calls for cease-fire had gone unheeded. Annan spoke at an emergency meeting of the council which he convened after that IDF air strike in Qana early Sunday. He said the council had a responsibility to demand an end to the violence. "We meet at a moment of extreme gravity first and foremost for the people of the Middle East but also for the authority of this organization and especially this council," Annan said. "Action is needed now before many more children, women and men become casualties of a conflict over which they have no control."
