A Qassam rocket fired by Palestinian gunmen in northern Gaza Monday evening toward the Sderot area apparently landed near the security fence separating Israel from the Hamas-controlled enclave.
It is still unclear whether the rocket landed within Palestinian or Israeli territory.
At around 6:50 the Color Red siren sounded in Sderot and in the Shaar Hanegev Regional Council, after which an explosion was heard. There were no reports of injury or damage.
The siren sounded as high-schoolers in Sderot were taking their matriculation exam in history. Ilan Abukasis, a deputy administrator at one of the local schools told Ynet "when we heard the alert we immediately stopped the exam and instructed the students and proctors to leave the classroom and head a secure area. They returned to the classroom a few minutes later."
Earlier Monday, several mortar shellsfired from Gaza landed in an open area within the Eshkol Regional Council. There were no reports of injuries or damage in the barrage, which took place just before noon.
Shortly afterwards, the Israel Defense Forces attacked a vehicle in the Gaza town of Rafah, reportedly injuring a number of people. One of the wounded, a member of the Popular Resistance Committees, died at the hospital. Two others sustained serious injuries.
Sunday night saw the Israeli Air Force strike a number of targets in Gaza, including a Hamas stronghold and several smuggling tunnels on the Philadelphi Route. Witnesses said the attack triggered several explosions, indicating that Hamas as resumed its arms smugglings. No casualties were reported.
The strike came in retaliation for the launching of four Qassam rockets and 13 mortars toward Israel.
