Grad rockets landed near the cities of Netivot and Ofakim in the western Negev on Monday, causing damage to a car and leading to four people being treated for shock.

The attacks came a few minutes apart late Monday. One rocket hit Netivot, which is 9 miles east of Gaza, and the second exploded in Ofakim, 15 miles from Gaza.

There was no immediate claim of responsibility.

Last month saw an increase in rocket attacks from Gaza, with over 13 rockets striking the western Negev over the course of two days, in one particular instance.

A Qassam rocket that struck near a kindergarten in Ashkelon lightly wounded a teenage girl in a nearby building.

According to the IDF spokesman's office, over 200 Grad missiles, Qassam rockets and mortar shells were fired from the Gaza Strip into Israeli territory in 2010.

Rocket fire usually draws retaliatory Israeli airstrikes at Gaza militant facilities or smuggling tunnels.
