Israel carried out air strikes in the Gaza Strip early on this morning, hitting fields and roads believed to be used by militants for rocket attacks on Israel.
Palestinian security sources said Israeli aircraft fired two missiles at a road in central Gaza, missing a car carrying militants.
The missiles left large holes in the road, witnesses said. An Israeli army spokeswoman said the air strike in central Gaza targeted rocket-launching sites used by militants.
Palestinian security sources said Israeli missiles also struck two roads in northern Gaza.
There were no immediate reports of casualties.
The Israeli army has frequently carried such raids in order to cut roads used by militants to transfer rockets to launching sites.
The latest attack comes nearly a week after Israeli aircraft killed the top bomb maker for Islamic Jihad and another gunman in an air raid in Gaza City.
Islamic Jihad had just claimed responsibility for one of the worst recent rocket strikes from Gaza on Israel, in which three Israelis were wounded, including a baby.
