GAZA CITY, Gaza Strip (AP) — Israeli airstrikes against Palestinian militant targets in the Gaza Strip have continued for a third day. The Palestinian death toll has risen to 31 as foreign mediators press ahead with efforts to reach a cease-fire. After the Palestinian Islamic Jihad militant group fired longer-range rockets toward Israel, Israeli warplanes struck Islamic Jihad rocket launchers. There were no immediate reports of casualties. Despite those sporadic Israeli strikes, the situation early Friday was relatively calm. Islamic Jihad held its rocket fire overnight, raising hopes that Egypt, Qatar and the United Nations would be able to broker a cease-fire.
