Israeli fighter jets hit 25 targets in the Gaza Strip early today in response to rocket fire from the Palestinian territory, the army said.
The military said 25 targets linked to the militant Hamas movement were hit, in response to a barrage of about 45 rockets and mortar shells.
Residents reportedly said two Hamas security personnel were slightly hurt. No Israeli casualties were reported.
The strikes follow weeks of confrontation along the Gaza border.
More than 120 Palestinians have been killed by Israeli forces and thousands more wounded since a protest campaign began on 30 March, Gaza’s health ministry says.
UN Secretary General Antonio Guterres and other international stakeholders have warned that Gaza is close to the brink of war.
The Israeli military said that Hamas targets, including a number of bases, were struck in three rounds of strikes overnight.
Air raid sirens and phone warning systems sounded before dawn in Israel.
The military said Iron Dome missile defence system intercepted seven rockets fired by militants. Kites carrying containers of burning fuel were also sent into Israel, the military said.
Israel and Hamas have fought three wars since 2008 and observe a tense ceasefire that is regularly shaken by hostile acts.
