Gaza's Hamas rulers are asking the Arab states to cut ties with Israel, and support Hamas's armed campaign against it instead.
About 2,000 people were attending a Hamas-organized rally in Gaza, as Arab leaders convened in Damascus ahead of the annual Arab summit.
Hamas leader Khalil al-Haya said Israel would only respond to violence. "The Zionist enemy doesn't have a vision of peace. Only force ... fighting and holy war works with (Israel)."
