The conflict between Israel and Hamas is continuing into its third week, with Israel dropping leaflets on the Gaza Strip warning residents it will escalate its military action.
Correspondents say the next phase could see Israeli forces moving deeper into cities and refugee camps - that will involve new risks for Israeli soldiers and civilians in the Gaza Strip.
Israel carried out dozens of air strikes on Gaza on Saturday, while Hamas fired rockets into southern Israel. Medical officials say more than 800 Palestinians have died. Thirteen Israelis have been killed.
Two Israelis were injured on Saturday as rockets hit the coastal town of Ashkelon (pictured). Meanwhile eight people who appeared to be civilians died in Israeli fire in Jabaliya, Gaza, Palestinian medics said.
Thousands of people have been injured. The bloodshed continues after Hamas and Israel ignored a UN resolution on Thursday calling for an immediate and durable cease-fire.
Aid agencies say Gaza's 1.5 million residents urgently need food and medical aid. The UN has resumed aid distribution after halting it on Thursday when it said one of its drivers died in Israeli fire.
Palestinian Authority President Mahmoud Abbas urged all sides to accept a truce, as he met Egyptian President Hosni Mubarak in Cairo. But analysts say his remarks will have little impact.
Demonstrations were held across Europe in protest against Israel's action in Gaza. Thousands gathered for Britain's biggest pro-Palestine protest in London.
Protests also continued in the Middle East, as well as parts of Africa and Asia.
