<m> killed </m> in An Israeli mortar strike that killed about 40 Palestinians sheltering in a UN school Tuesday brought new urgency to diplomatic efforts to end Israel's military onslaught in the Gaza Strip. The Israeli army said the UN school in the Jabaliya refugee camp was hit when troops responded to a mortar attack from the grounds and that the dead included a number of Hamas militants. The casualties appeared to intensify international efforts to arrange a cease-fire after 11 days of a punishing Israeli offensive against Hamas.
