Airstrikes rained down on Gaza on Monday (September 13).
Israel carried out the attack in response to Palestinian rocket fire on its territory for a third consecutive night, according to the Israeli military.
Fighting between the Palestinians and Israel has escalated over the past week, after six Palestinian militants escaped from a maximum-security prison in Israel on September 6.
Israeli forces have since captured four of the inmates.
Gaza militants fired a rocket into Israel on Friday (September 10) when two of the prisoners were apprehended.
And then again on Saturday, after two more inmates were caught.
The Israeli army said rockets were intercepted by Israel's Iron Dome missile defense system.
No casualties were reported.
The Israeli military said it struck targets belonging to Hamas, the Islamist armed group that rules Gaza.
The recent rise in cross-border violence tests a fragile truce between Gaza and Israel that ended fierce fighting in May.
