Israel has launched a series of strikes on the Gaza Strip in what it calls a retaliation for a suicide bombing that killed five Israelis in Netanya Monday. Islamic Jihad, which carried out the bombing, had called that attack a response to Israeli assaults on its members. On Wednesday, an Israeli warplane killed Mahmud al-Arqan, a top member of the local Popular Resistance Committees. Ten other people were wounded in the attack, including three children struck by shrapnel.
