Palestinian militants in Gaza have fired two rockets into southern Israel, causing no casualties but triggering a series of Israeli air raids.
No one was hurt in either of the attacks.
One of the rockets hit a parked bus in the town of Sderot, while the Israeli army said the second was destroyed by its "Iron Dome" defence system over the town of Ashkelon.
Israeli warplanes then bombed a base of the Ezzedine al-Qassam Brigades, the military wing of Hamas, in northern Gaza, according to a witness and a security official in Gaza.
The security official said the air raid caused no casualties.
The rocket fire has not yet been claimed by any group.
