Four Kassam rockets were fired at Israel on Friday, causing no injuries and no damage.
Two rockets fired from the northern Gaza Strip landed in two communities south of Ashkelon.
On Friday afternoon, Palestinian policemen defused two Kassams found in a launch pad in the northern Strip.
Earlier Friday, the IDF’s Red Dawn alert system identified two rockets fired at Sderot. The rockets exploded in an open field north of the city, IDF officials said.
The IDF said its latest offensive of firing artillery rounds, targeted assassinations and aerial strikes at active cells, dealt a severe blow to terror groups and lead to a decrease in the number of Qassams fired from the Gaza Strip.
Security officials have decided to impose a full closure on Palestinian areas starting Saturday night. The curfew will remain in place until Wednesday.
The decision to impose the curfew ahead of the upcoming Purim holiday was taken during the weekly situation assessment undertaken Friday morning.
Defense Minister Shaul Mofaz instructed the IDF and defense establishment to undertake the utmost effort - including the cancellation of training sessions and leaves if necessary - to thwart terror attacks ahead of the Purim holiday and upcoming elections.
