The airstrikes allegedly came in retaliation for a barrage of 150 rockets fired into Israel on Wednesday evening, of which 25 were shot down by the Iron Dome defense system.
"We responded by targeting a cement factory used by Hamas to build terror tunnels, a maritime terror tunnel shaft, & several terror sites in military compounds," the IDF tweeted.
IDF also reported that an Israeli fighter jet had fired towards what it called a "rocket launching squad" in Gaza.
A spokesman for the Gaza health authority said earlier that a Palestinian died in Gaza on Wednesday after Israel shelled the exclave allegedly in retaliation to rockets fired into its territory.
"A 30-year-old Palestinian man died in a shelling near the city of Beit Lakhia. Six people have been injured so far as a result of Israeli aggression," Ashraf Qidra told Sputnik.

The military said it had responded by launching an airstrike at a vehicle allegedly used by another "rocket launching squad" in Gaza to fire a rocket at Israel.
