The Israel Defense Forces launched airstrikes in the Gaza Strip late Saturday night in retaliation for airborne arson attacks from the coastal enclave and renewed riots along the border.

The raids on Hamas targets south of Gaza City came hours after two fires were sparked in southern Israel by balloon-borne incendiary devices launched from the Gaza Strip. Hours later, Palestinians resumed clashes with Israeli forces along the Gaza border, as Hamas threatened to step up the cross-border arson attacks from Sunday.

The military said the airstrikes targeted a Hamas military compound used for training and weapon production, and the opening of a “terror tunnel.”

“The IDF will continue to respond forcefully against Hamas’s terror attempts,” the army said, underlining that its raids were in response to both the fires and border violence.

The Hamas-run health ministry in Gaza on Saturday night said 11 Palestinians were wounded in the border clashes with Israeli troops. According to the ministry, three of those wounded were hit by live fire and are in moderate condition. The other eight are said to have been lightly hurt from rubber bullets or shock grenades. It was not immediately clear if the Israeli airstrikes on Saturday night caused injury or damage.
