Representatives of Palestinian factions Hamas and Fatah returned to Cairo on Tuesday to resume talks on forming a "national unity" government, representatives of the groups said. The Egyptian-mediated talks between Hamas, which controls the Gaza Strip, and Palestinian President Mahmoud Abbas' Fatah faction, which controls the West Bank, were scheduled to resume on Tuesday, ahead of a broader meeting including more factions on Wednesday. "The talks will focus on the issues that were not solved in the last round of talks," Hamas spokesman Fawzi Barhoum told the German Press Agency 'DPA' on Tuesday.
