The rocket fire emanating from Gaza subsided Sunday evening, but one Qassam did hit a shed in a kibbutz located in the Eshkol Regional Council in south Israel. A kibbutz volunteer was treated for very light injuries.
"No one was hysterical, but the volunteer appeared a bit shaken up," kibbutz member Yohai Kopler said. "He was walking by the shed and was hit by shrapnel."
At least five mortar shells were launched at the western Negev during the afternoon and evening hours, but there were no reports of injuries or damage in the attacks.
Meanwhile, Israeli aircraft struck dozens of Hamas targets Sunday evening.
Al-Jazeera reported that a senior figure in Hamas' armed wing, the Izz al-Din al-Qassam Brigades, was killed during an aerial strike on his home in east Gaza.
According to the report, the Air Force struck additional homes belonging to members of the armed wing.
Series of strikes
Israeli warplanes were also said to have bombed the Islamic University in the Gaza. Witnesses said a series of explosions rocked the Gaza city campus.
Palestinian sources in Gaza said the Air Force also attacked the Shati refugee camp in the western part of the coastal enclave, in close proximity to the home of Hamas Prime Minister Ismail Haniyeh.
Several Hamas websites reported Sunday that the IAF targeted a residential building in the east Gaza Strip neighborhood of Zeitun.
According to the report, the house was destroyed. Aircraft also bombed metal workshop in the neighborhood.
The Palestinian news agency Ma'an reported of additional attacks on an outpost that once served as the Preventive Security cadre's headquarters in south Gaza, another position that once housed General Intelligence headquarters and on the Palestinian Olympic Committee building.
An Egyptian security official said forces have managed to seal most of the breaches along the border with Gaza, just hours after hundreds of Palestinians crossed over to the Egyptian side.
He added that most of the Palestinians have returned to the Strip.
