The Israeli newspaper Haaretz reports the Israeli military has accelerated its planning for what it describes as an extended military operation in Gaza. This comes as fighting continues between the Palestinian factions Hamas and Fatah. At least 20 Palestinians have died since Friday. Fighting continued over the weekend despite calls for a ceasefire. Fatah leader Mahmoud Abbas and Khaled Meshal of Hamas are scheduled to meet for talks in Mecca, Saudi Arabia, on Tuesday.
