A series of Israeli violations of the Gaza Strip cease fire have sparked concern among residents of the Palestinian enclave that an escalation of tensions could lead Tel Aviv to launch a renewed offensive. At least 11 cases of Israel opening fire on Palestinians have been reported in the past week alone. Meanwhile, the Islamic State launched 5 bomb attacks in Gaza City on Sunday, the first time such incidents have occurred since Hamas took power, further stoking residents' fears.
