According to Hamas security source, multiple missiles have struck and caused serious damage, but no casualties, on Hamas’ al-Qassam infrastructure.

Israeli forces said that its warplanes, combat helicopters, and tanks hit a number of targets belonging to the Hamas terror group. An Israeli military spokesperson said all actions against Israel are serious and Israel will retaliate activities harmful to its people.

Israel has continuously threatened to launch a strong attack on Hamas group in the Gaza if the group continues to release balloons with explosives from the Gaza into Israeli territory.

Dozens of balloon-borne devices were launched into southern Israel on Tuesday and Wednesday, igniting over 80 fires.
