An Israeli helicopter fired missiles at a car carrying members of the militant Hamas group in Gaza City, wounding one of them and about 10 bystanders.
The Israeli army had no immediate comment on the attack, the second missile strike in Gaza in less than a week following the recent failure of Egyptian-mediated ceasefire efforts.
Two missiles slammed into the vehicle in Gaza's Sheikh Radwan neighbourhood, a Hamas stronghold, after nightfall, but three of its four passengers escaped injury, sources said.
The passengers belonged to Izz el-Deen al-Qassam, the armed wing of Hamas, a Palestinian group that has carried out dozens of suicide bombings in Israel since the start of an uprising in September 2000.
None of the passersby hurt in the missile strike by shrapnel and flying glass sustained life-threatening injuries, medics said.
