A Palestinian child wounded in an Israeli air strike on Gaza arrives at the Rafah border crossing between the Gaza Strip and Egypt for treatment in an Egyptian hospital on January 13, 2009. Senior Hamas leader Mussa Abu Marzuk said today as a Hamas delegation held a fresh round of talks with Egyptian intelligence chief Omar Suleiman in Cairo that there is "a chance" that his Palestinian Islamist movement at war with Israel will accept a modified Egyptian ceasefire plan for Gaza. Until now, more than 900 Palestinians were killed and 4,000 wounded in Israel's offensive on Gaza which started on December 27, according to medical sources.
