Israel Defense Forces confirmed Nov. 14 that it had killed Ahmed Jabari, the leader of Hamas' armed wing, the Izz al-Deen al-Qassam Brigades. The airstrike that killed Jabari came a day after Israel warned that it was considering targeted assassinations in response to increasing rocket fire from Gaza. In addition to the strike on Jabari, the Israeli air force reportedly attacked a cache of 20 long-range missiles and a Gaza police station, and loud explosions are being reported in Gaza City. An IDF spokesman announced that the Israeli military was embarking on Operation Pillar of Defense, which could include a ground incursion into Gaza. The assassination of Jabari seems to have been a first salvo, one that will provoke retaliation from Hamas and that could affect Jordan and Syria. Renewed and expanded bouts of rocket fire are certain, including rockets targeting urban areas. But the question is what other operations Hamas can and will conduct.
