"A short while ago, a terrorist squad was launching arson balloons from the northern Gaza Strip into Israeli territory. In response, an IDF aircraft fired towards the squad," the IDF said on Twitter.
No casualties from the airstrike have been reported so far.
This is the second time that Israeli forces have responded to Palestinians' actions with fire since the two parties announced a truce early on Saturday.
Israel views the launch of arson balloons into its territories as a Palestinian terrorist campaign and responds with military force, economic sanctions and threats to conduct a large-scale military operation in the Gaza Strip.
On Saturday, a top-level source in Jerusalem told Sputnik that Hamas had agreed to accept Israel's demands and stop clashes between protesters and the police in the border area, as well as halt launches of arson balloons.
