The Israeli army said it launched strikes Tuesday on a position belonging to the Islamist movement Hamas in the Gaza Strip, after gunfire from the Palestinian enclave.

"Following the firing of a bullet from the Gaza Strip into Israel, the IDF (military) is currently striking a Hamas military post in the northern Gaza Strip," the army said in a statement.

A witness in Gaza's Beit Hanoun area told AFP they saw multiple strikes on a security site controlled by Hamas, the militant group which rules the enclave.

"Earlier today (Tuesday), a bullet was found in the community of Netiv Haasara," the army said, referring to an Israeli agricultural community adjacent to Gaza's northern border.

"After an inquiry, it was found that the bullet hit an industrial building earlier today after being fired from the Gaza Strip," the army added.

The latest strikes come after Israeli warplanes targeted a Hamas site in the Gaza Strip on the weekend in response to rocket fire from the enclave, the military said.

Prime Minister Yair Lapid said Sunday that Israel will respond "quickly, forcefully and without hesitation" to any fire from Gaza.
