"Thank God we survived this time and got out alive from here. But we don't know how long we'll be safe in my brother's home," Mussa, 35, said by telephone.

The Israeli military said it carried out dozens of airstrikes on squads of gunmen, rocket launching sites and smuggling tunnels along the Egyptian border.

The Gaza fighting has raised tensions around the region and galvanized anger toward Israel throughout the Arab world. On Tuesday, at least one gunman opened fire at an Israeli army patrol along the desert border between Israel and Jordan, the military said. There were no casualties, and Jordan said the claim was "baseless."

In the southern West Bank city of Hebron, the Israeli military said, a Palestinian was shot and injured after he tried to grab a gun from an Israeli soldier whose patrol stopped him for questioning. The man later died, according to an Associated Press reporter who saw his body.

Humanitarian concerns have increased amid the onslaught although some aid is getting through to Gaza during daily three-hour lulls declared by Israel to allow delivery of supplies.

In Brussels, the European Union's aid chief said Israel has not respected international humanitarian aid during the war. In Oslo, Norway, the head of the U.N. agency for Palestinian refugees, Karen Abu Zayd, urged the Israeli army to do more to allow supplies into the besieged area.

"We are getting a lot of help from the Israeli Defense Forces on the one crossing that's open to get more and more trucks in, but it's just not enough," she said.
