As children were again rushed into hospital in Gaza, it was almost as if there had never been a three-day truce.
The most vulnerable are again paying the biggest price for renewed fighting between Israel and Hamas.
As one side blames the other for the failure of talks in Cairo, the death toll rose by at least five in Gaza on Friday, including a ten-year-old boy.
Israel says Hamas fired first and uses civilians as human shields. It rejects claims its response is disproportionate.
“First of all we must continue to act with force,” Justice Minister Tzipi Livni told Israel’s Channel 2 television on Friday evening.
“They are firing at us and they have to get hit in return – and not in the same proportion – but to a greater extent.”
Two Israelis were injured by mortars on Friday. Officials say dozens of rockets were unleashed across the border. Israel insists it won’t negotiate under fire.
Islamic Jihad and the Popular Resistance Committees claim they were behind the salvoes rather than Hamas.
A month after the start of hostilities, the UN says more than 1,900 Palestinians, mainly civilians, have died as have 67 people on the Israeli side, almost all of them soldiers.
