A 10-year-old boy was among seven Palestinians killed on Friday when Israeli tanks and helicopters opened fire inside the Gaza Strip after Israel vowed to retaliate for a border attack.

Gaza fighters Wednesday breached the border with Israel under cover of mortar fire, killing two Israeli contractors at the Nahal Oz oil terminal that provides the Palestinian territory with its fuel supplies. On the Palestinian side, four civilians and three fighters were killed during and immediately after the attack. Israel said it temporarily shut down the terminal, but insisted it would continue providing minimal fuel supplies to the Palestinian territory that has been under a crippling blockade for months. Hamas this week threatened to storm Gaza's borders in a repeat of a breach in January that sent hundreds of thousands of weary Palestinians streaming into Egypt to stock up on goods they can't get at home because of a tight Israeli
