An IDF drone fired two missiles at rocket launchers in the northern Gaza Strip used to fire Qassams at Sderot, Israel Radio reported early Tuesday morning.
On Monday evening three Qassams landed in Sderot following a day of fighting in the Gaza Strip that left seven Palestinians dead.
Several people were treated for shock after two rockets hit the western Negev town, damaging three cars.
A third rocket hit an open area between Sderot and Kibbutz Or Haner.
At least seven Palestinians, including three civilians, were killed and 35others injured in a clash between armed militants and Israel Defense Forces soldiers in the northern Gaza Strip on Monday.
Four of the dead men were armed and one was a senior member of the Popular Resistance Committees (PRC).
The PRC, an umbrella of Palestinian militant groups in Gaza, said the target of the IDF operation appeared to be Ata Shindari, who led the group's rocket-launching branch.
Shindari and one of his brothers were killed by the IDF, Abu Abir, the group's spokesman said.
PRC spokesman Abu Abir vowed revenge for Shimbari's death.
"This is the calm before the storm," he told a news conference.
Palestinian hospital officials said the dead included three brothers and their cousin.
Some 20 other Palestinians were wounded by gunfire near the village of Beit Hanun.
Palestinian Authority Chairman Mahmoud Abbas said the IDF operation in northern Gaza was a "loathsome massacre carried out, of all days, on the first day of Eid al-Fitr."
Abbas called on the international community to intervene in order to prevent a further deterioration.

Gunfire at a mourning tentLocal residents said IDF fire initially killed three gunmen paying a condolence call at a mourning tent set up by a family of a militant shot dead by IDF soldiers in an earlier incident.

Realizing their mistake, they then directed their fire towards IDF troops and a gun battle ensued, the residents said.
When the smoke cleared, seven Palestinians were dead and some 20 wounded, a Palestinian Health Ministry official said, blaming IDF gunfire for all the casualties and basing his account on information from ambulance crews at the scene.
