JERUSALEM (AP) -- A rocket launched from the Gaza Strip has struck the yard of a house in southern Israel following an overnight lull in cross-border exchanges of fire.
Police spokesman Micky Rosenfeld says no one was injured in the explosion Monday.
Earlier, Israeli aircraft struck three militant sites in Gaza, responding to recent rocket barrages.
The military says more than 110 rockets have hit Israel since Saturday.
The Israeli government is under stiff pressure to put an end to the attacks, which intensified over the weekend and have drawn retaliatory Israeli airstrikes.
The violence threatens to explode into a major confrontation ahead of Israel's Jan. 22 elections.
Israeli leaders have warned they won't tolerate continued assaults. Defense Minister Ehud Barak says elections won't constrain Israel from acting to halt the rocket fire.
