The IDF on Sunday said it fired at a group of Palestinians flying incendiary balloons into southern Israel from the northern Gaza Strip.
Reports in Palestinian media said one person was injured by the Israeli drone strike in the Beit Hanoun area.
In a statement, the army said the Palestinians were members of the Hamas terrorist organization that rules the Strip.
The strike came hours after a fragile ceasefire between Israel and Hamas went into effect, following the most severe exchange of fire between Israel and Hamas since the 2014 war.
Over the weekend, Palestinian terrorists fired some 200 rockets and missiles at Israeli communities near the Gaza border. In response, the IDF struck dozens of Hamas targets in the Strip.
