Quds, January 18, SPA -- Israel sealed all border crossings with the Gaza Strip Friday, cutting off the flow of vital supplies to the besieged territory in an attempt to stop Palestinian rocket barrages on Israeli border towns, according to AP. But violence continued Friday, with Israeli air strikes killing two civilians and one militant while Palestinians fired 16 rockets into southern Israel, including one that damaged a day care center. The bloodshed clouded U.S.-backed peace talks that Israel and Palestinian President Mahmoud Abbas' West Bank government renewed last month. The Gaza quagmire could complicate U.S. President George W. Bush's efforts to prod the sides toward a final peace deal by the end of the year.
