Rockets also landed near Tiberias. One woman, who suffered from shock, was evacuated to Poria Hospital. Damage to at least one building was reported.
In rocket barrages earlier Saturday afternoon, two Katyushas landed in a residential neighborhood in a Galilee community, causing damage but wounding no one.
Five other rockets landed in open territory. No wounded or damage was reported. Earlier, three rockets landed harmlessly in Safed.
Deputy Commander of the Northern Command, Brig.-Gen. Alon Friedman, said on Saturday that the missiles fired at Afula on Friday by Hizbullah were not Iranian Fajr-5s, as originally reported, but an older Syrian-made model.
Police reported Saturday that sappers have located remnants from 1646 rockets since the outbreak of violence in the North, but that the actual number of rockets fired was much higher, Israel Radio reported.
After a number of Katyusha barrages hit northern Israel over the course of the morning, five missiles landed near Afula shortly after 3:30 p.m. Friday. This was the first time missiles of this type have been fired at Israel by Hizbullah.
Police in the North said in an official statement that one of the missiles, which landed near Afula, contained 100 kg. of explosives - an amount that could have caused extensive damage and casualties had it struck a building.
No one was wounded in the attack, and the Home Front Command instructed residents of the city to remain indoors. The attack caused a fire, and a helicopter was scrambled to help firefighters contain the blaze.
In a statement released by Hizbullah, the group called the attack an "implementation of the promise and decision and in response to the brutal aggression (by Israel)."
Shortly after the attack, IAF jets destroyed the launcher.
Four people were moderately wounded and 12 lightly wounded when over 105 rockets landed in northern Israel on Friday afternoon. Fifteen people were suffering from shock.
Damage was caused to several buildings, including a hospital in Nahariya, a school, as well as to a high-tension wire, which caused power failures in some areas. The electric company was working to restore electricity.
Earlier Friday, a parked car was directly hit by a Katyusha rocket in Kiryat Shmona, destroying the vehicle but hurting no one.
Near Safed, rockets destroyed a local Magen David Adom building, the organization said. No one was hurt in the attack.
