Palestinians sleep at a United Nations school, where people who fled heavy Israeli shelling in the Shejaia neighbourhood sought refuge during fighting, in Gaza City July 21, 2014. Israeli forces killed at least 10 Palestinian militants on Monday after they crossed the border from Gaza through two tunnels, the military said, as the death toll from the two-week conflict passed 500. The overnight raids lifted the Palestinian death toll to 484, mostly civilians, since fighting started on July 8. Israel says 18 of its soldiers have also died along with two civilians.

Thousands fled their homes in a Gaza town on Sunday after Israel warned them to leave ahead of threatened attacks on rocket-launching sites, on the sixth day of an offensive that Palestinian officials said has killed at least 160 people. Militants in the Hamas-ruled Gaza Strip kept up rockets salvoes deep into the Jewish state and the worst bout of Israel-Palestinian bloodshed in two years showed no signs of abating, and Western foreign ministers meeting on Sunday said a ceasefire was an urgent priority.

Israel approved an Egyptian-proposed deal that would halt the week-old Gaza shelling war on Tuesday but the Palestinian territory’s dominant Hamas Islamists responded suspiciously, saying they had not been consulted by Cairo.

Palestinian children, who fled their family house that is adjacent to the border with Israel, sleep as they stay at a United Nations-run school in Gaza City July 13, 2014. An Israeli air strike on the home of Gaza’s police chief killed 18 people on Saturday, Gaza’s health ministry said, and Hamas fired the largest salvo of rockets yet on Tel Aviv since the start of the Jewish state’s offensive in the Palestinian enclave. Israel’s offensive has killed 145 Palestinians since Tuesday. Gaza medical officials said at least 82 civilians, including 25 children, were among the dead from the air strikes on the territory into which nearly 2 million people are packed.
