Tension Escalates As Rockets Criss Cross Sky Over Gaza

Warplanes, drones and rockets criss-crossed the sky over Gaza for the sixth day Monday as Israel pressed its air offensive against Gaza militants. Hamas leader Khaled Meshaal vowed continued resistance against what he called a "criminal enemy." "We do not want escalation nor do we call for a ground war," he told reporters at a news conference. "But we are not afraid of it nor will we back down."
