GAZA CITY, Gaza Strip ? Palestinian militants fired two rockets from Gaza into an Israeli village Sunday evening, despite Israeli airstrikes earlier in the day launched in response to previous attacks.

There were no serious injuries, but the exchanges carried the danger of sudden escalation. The rockets hit an Israeli village four miles from the Gaza fence, demonstrating a longer range than usual for the homemade rockets.

The Israeli airstrikes Sunday were the first since Oct. 27, the military said.

After Israel withdrew from Gaza in September, destroying all 21 Jewish settlements there, Israeli leaders pledged to retaliate for any Palestinian attacks from the territory. The military moved artillery to the Gaza-Israel border and has been pounding areas used by militants to launch rockets.

Early Sunday, Israel stepped up its attacks, sending its air force to blast Gaza targets three times. Palestinians said a bystander was slightly wounded in one of the strikes.

The military said one target was an Islamic Jihad charity that it called a front for terror-related activity. Missiles also hit open fields where homemade rockets had been launched in recent days, it said.
