Israeli troops have shot and killed a young Palestinian girl in the southern Gaza Strip, after militants fired mortar rounds at a nearby Jewish settlement.

Officials say the confrontation began when militants fired three mortars at the settlement near the Khan Younis refugee camp. Four Israelis, including one child, were hurt.

In response, the Israeli military fired into the refugee camp, killing the young girl.

Palestinian militants often fire homemade mortars and missiles into Jewish settlements in Gaza, but they rarely cause any injury or damage.
