The Israeli military launched an airstrike in Gaza in response to riots during a protest rally at the border, in which many Palestinians were injured, according to medical sources.

The strike was the first since early July, when Israel responded to rockets fired from the Gaza Strip in response to Israeli military operations in the West Bank. The Israeli military said the target was “a position of the terrorist organization Hamas in the northern Gaza Strip.” A spokesman said a zone where many Palestinians had gathered earlier, near the Karni border crossing, was targeted, which remains closed.

A Gaza security source told AFP that Israel “shelled a resistance observation post in the east of Gaza City.”

No injuries were reported.

Earlier, an AFP reporter present at the demonstration saw Palestinians throwing stones and Molotov cocktails at Israeli forces on the other side of the border. Two protesters were injured by bullets. Thick black smoke covered the area as Palestinians set tires on fire.

Gaza’s health ministry said a total of 12 Palestinians were injured in various rallies along the border.

The Israeli military said “several explosive devices” were fired at the soldiers, but no one was injured.
