Palestinian firefighters try to extinguish a burning building after an Israeli missile strike in the Rafah refugee camp, southern Gaza Strip, Sunday, Dec. 28, 2008. Israeli warplanes pressing one of Israel’s deadliest assaults ever on Palestinian militants dropped bombs and missiles on a top security installation and dozens of other targets across Hamas-ruled Gaza on Sunday. Israel’s Cabinet authorized a callup of at least 6,500 reserve soldiers, suggesting plans to expand an offensive against Gaza rocket squads that has already killed some 280 Palestinians.
