Meanwhile, rockets fired by Hizbullah on Friday evening landed near the Syrian city of Kuneitra located several kilometers east of the Golan Heights. No injuries or damage were reported.
The IDF said that the firing at Kuneitra represented yet another attempt to drag Syria into the conflict.
Earlier, a Hizbullah-fired rocket killed a 27-year-old woman in Mughar, making this the third time the Druze-Muslim-Christian village was struck by rockets.
She was later identified as Manal Azzam, a mother of two young children. She was also buried on Saturday afternoon.
According to reports, Azzam heard the warning siren and entered an inner room in her home, which did not have a shelter, and was killed when the rocket directly struck the house. Two other people were seriously wounded in the town.
Elsewhere, an IDF reservist was seriously wounded by a Katyusha rocket in the Galilee. His family has been notified.
Another person was critically wounded in Kibbutz Sha'ar Yishuv near Kiryat Shmona, while in Safed, two were lightly wounded and two suffered shock. Two more people were lightly wounded by shrapnel and eight suffered from shock in the village of Hurfeish in the upper Galilee.
The Home Front Command ordered residents across the North to remain in shelters or protected areas.
Police commander Dan Ronen said 70 rockets crashed into towns across the north in under an hour. A total of 135 rockets were fired at northern Israel by Friday afternoon.
Warning sirens sounded all over the North shortly before the barrage, from Safed to Acre and Zichron Ya'akov. Sirens were also heard in the Golan Heights.
Earlier Friday, rockets landed in the Kiryat Shmona area. No one was wounded in that attack.
On Thursday, over 180 rockets were fired at northern Israel, killing eight civilians and wounding many others.
