The head of the United Nations refugee agency warned Sunday that civilians in Lebanon were caught in the crossfire as Israel's intensified bombardment campaign forced many to flee while others were trapped under fire. Israel has launched an intense bombing campaign against Hezbollah since September 23, killing more than 1,100 people and pushing upwards of a million people to flee their homes, officials said. "We estimate, and probably our estimate is conservative, that 220,000 have crossed the Lebanese-Syrian border," Filippo Grandi said, adding that 70 percent were Syrians and the rest Lebanese.
