Hamas is in for an ass whooping.

JERUSALEM (AP) — The Israeli military launched what could be a long-term offensive against the Hamas-ruled Gaza Strip on Tuesday striking nearly 100 sites in Gaza and mobilizing troops for a possible ground invasion aimed at stopping a heavy barrage of rocket attacks against Israel.

The military said “Operation Protective Edge” looks to strike the Islamic Hamas group and end the rocket fire that has reached deeper into Israel and intensified in recent weeks.

The attacks come as tensions have soared over the killing of three Israeli teenagers and the apparent revenge killing of a Palestinian teenager by three Jewish suspects.

The military said it was seeking to “retrieve stability to the residents of southern Israel, eliminate Hamas’ capabilities and destroy terror infrastructure operating against the State of Israel and its civilians.”

Nearly 300 rockets and mortars have been fired at Israel in recent weeks, including a barrage of close to 100 projectiles on Monday alone, the military said, a huge surge after years of relative quiet that followed a previous Israeli campaign to root out Gaza rocket launchers.
