The Air Force struck 29 targets across the Gaza Strip on Wednesday night in response to a large-scale Islamic Jihad rocket attack.
The bombardment of the western Negev marks the largest flare-up of Gazan terrorism since 2012.
At least 60 rockets – fired in simultaneous barrages from northern and southern Gaza – exploded in Israeli territory.
The Iron Dome anti-rocket battery stationed in Sderot shot down three projectiles over the town.
Eight rockets exploded in built-up areas, but none caused injuries, the army said.
IDF tanks on the Gaza border struck two terrorist targets inside the Strip soon after the rocket attacks.
