Security forces and neighbors examine the aftermath Saturday of a direct Katyusha rocket hit on a house in Moshav Lehman, an Israeli camping village 21/2 miles south of the border with Lebanon. The rocket, one of a dozen launched from Lebanon by Hezbollah guerrillas, penetrated the house through the roof, then exited through a wall before exploding next to the car below. Three children sleeping in a room near where the rocket landed were injured slightly. The guerrillas said the attack avenged an Israeli air raid Thursday.
