Jerusalem ? Israel withdrew its troops from the Gaza Strip on Saturday after some of the fiercest gunbattles with Palestinian militants in the Hamas-run territory since last year’s military offensive.

Israeli troops used bulldozers to “remove infrastructure used by terrorists to attack soldiers” before the early morning withdrawal, a military spokeswoman said.

Gaza militants, meanwhile, fired a rocket into southern Israel on Saturday, but no injuries were reported, the military said. Two others fell short of Israeli territory.
