Arson attacks pelted southern Israel again on Monday despite the ceasefire with Hamas, igniting a number of fires.
The IDF responded in the afternoon with airstrikes against two Hamas positions in northern Gaza, the area from which balloons were launched.
Palestinian sources said the drone strike was near Beit Hanoun and left several wounded.
Subsequently, a projectile fired from Gaza at Israel reportedly fell short of the Gaza border. But it triggered air-raid sirens in the town of Zikim near the border, causing two explosions that could be heard by local residents.
The airborne arson started a fire near the Gaza border community of Kissufim in the Eshkol Regional Council. Firefighters were dispatched to extinguish it, as well as fires in three other nearby communities.
