Explosion and smoke rise following an Israeli strike in Gaza, seen from the Israel Gaza Border, southern Israel, Saturday, Nov. 17, 2012. Israel bombarded the Hamas-ruled Gaza Strip with more than 180 airstrikes early Saturday, the military said, widening a blistering assault on militant operations to include the prime minister's headquarters, a police compound and a vast network of smuggling tunnels. The new attacks followed an unprecedented rocket strike aimed at the contested holy city of Jerusalem that raised the stakes in Israel's violent confrontation with Palestinian militants.
