Hamas and Fatah officials met to try to calm tensions on Monday after a new Hamas militia battled gunmen from a Fatah-dominated force near Gaza's Palestinian parliament in clashes that killed a Jordanian diplomat's driver. Six bystanders were wounded as the rival groups traded fire from rooftops, behind buildings and on a Gaza City street in the latest internal fighting that will add to fears of civil war erupting in the impoverished territory of 1.4 million people.The Hamas and Fatah leaders were brought together by Egyptian mediators after which they both condemned the driver's killing and sent condolences to the Jordanian people and to King Abdullah. They agreed to hold daily meetings to try to calm tensions and sent a message to their respective gunmen that they would not protect them if they violate public order.
