Western Negev residents told Ynet that the Color Red alert system was activated, followed by two strong blasts.
One of the rockets landed inside Sycamore Ranch, which belongs to the family of former Prime Minister Ariel Sharon. Sappers who were dispatched to the area are expected to determine whether the rockets were improved Qassams.
Three mortar shells were later also fired from the northern Strip, landing in an open area near Kibbutz Kissufim. There were no reports of injuries or damage.
Earlier Sunday, two Qassam rockets landed in open areas in the Eshkol Regional Council in the southern western Negev. There were no reports of injuries.
Two Qassam rockets were fired at the western Negev at around 6 pm. One rocket landed near Sderot. Another rocket hit a kibbutz south of Asheklon. A third rocket launched several minutes later landed near a community in the Sha'ar Hanegev Regional Council.
There were no reports of injuries or damage in all incidents.
The third rocket landed near a reunion event of a paratroopers company from August 1962, which was attended by Deputy Defense Minister Matan Vilna'i, one of the company's squad commanders.
