Two Qassam rockets landed in open territory north of Gaza. One rocket fell not far from Kibbutz Zikim. Later another rocket landed in an open field near Sderot. There were no injuries or damage in either incident.
Islamic Jihad and Fatah's military wing, the al-Aqsa Martyrs' Brigades, claimed responsibility for the attacks.
Over the weekend, at least five attempts to fire rockets at Israel were identified.
On Thursday, Southern Command Chief Yoav Galant said that the activities of terror organizations would shape Israel's operations and response.
The IDF has completed a series of intensive operations against Qassam rocket launching cells in "Operation Lightening Strike."
The army is already prepared for the next operation, which could be harsher. The operation will be launched in accordance with a situation analysis held by the Southern Command.
The IDF refrained from firing artillery at Qassam rocket launch zones in northern Gaza, using only aerial attacks on a number of launch sites, but the latest Qassam shooting may change this.
The IDF said that it would not return to 'normal routine' due to the Qassams, which it said it would respond to accordingly.
"We are the ones who will decide the policy, both now and in the future," said an army source.
