Israeli jets struck two Hamas targets in the Gaza Strip overnight Tuesday, injuring at least three people, hours after a rocket fired from the Palestinian enclave hit an open area in southern Israel.

The Israeli military said in a statement that in response to the projectile attack in the Hof Ashkelon Regional Council earlier Tuesday, “IAF aircraft targeted two Hamas posts in the northern Gaza Strip.”

A Gaza security source told AFP that Israeli warplanes had struck two bases belonging to Hamas’ military wing, causing significant damage.

A medical official at the Shifa Hospital in Gaza City said three people were being treated for injuries, including a 26-year-old man who was in critical condition after being struck in the head with shrapnel.

Videos and photos, allegedly of the Israeli strikes, were circulating on social media.
