Israel says it carried out air strikes in Gaza overnight after Palestinians launched incendiary balloons from the territory, in the first major flare-up since an 11-day conflict last month.
The Israeli military said it targeted compounds belonging to Hamas, the militant group that controls Gaza.
The incendiary balloons sparked 20 fires in southern Israel on Tuesday.
Hamas said they were a response to a march by Israeli nationalists in occupied East Jerusalem
It said “terrorist activity” took place in the compounds, and that the IDF was “prepared for all scenarios, including the resumption of hostilities, in the face of continued terror acts from the Gaza Strip”.
The Palestinian news agency Wafa reported that aircraft bombed a site in the Maen area, south of Khan Younis, and another south of Gaza City, causing material damage.
A Hamas spokesman said on Twitter that Palestinians would continue to pursue their “brave resistance and defend their rights and sacred sites” in Jerusalem.
