Panic on the streets of Gaza as the wounded are rushed to the hospital.
At least three Palestinians were killed in an Israeli strike on southern Gaza.
Earlier Monday Israeli Prime Minister Benjamin Netanyahu warned of a protracted war in Gaza, dashing any hopes of a swift end to the three-week conflict as Palestinian fighters launched an audacious cross-border raid.
More than 1,000 Palestinians, mostly civilians have died in the conflict. Israel has lost 48 soldiers and three civilians.
As night fell army flares filled the skies. The Israeli military warned thousands of Palestinians to flee their homes in areas around Gaza City - usually the prelude to major strikes.
