Two rockets fell near the Israel-Gaza border fence late on Saturday night.
No warning sirens were heard and the military was initially unsure whether the projectiles struck the Israeli or Gazan side of the border.
Hamas on Friday vowed to avenge the death of Ali Dawabsha, who was killed in a terror attack when his house was firebombed. The terror attack was attributed to settler extremists.
On Friday, defense officials predicted that the Gaza terror group might launch rockets against Israel following the attack.
There were numerous West Bank and East Jerusalem flash points where Palestinian rioters clashed with Israeli security forces on Friday and on Saturday. No rockets were fired from the Strip on Friday.
Sporadic rocket fire over the past two months was often attributed to struggles inside Gaza between Hamas and Salafist groups which oppose Hamas rule.
The army’s official policy is to retaliate to attacks based on their damage, not the attackers’ intent. Misfired rockets landing on the Gaza side of the fence do not generally elicit an Israeli response.
