No casualties were reported at the moment.

On Tuesday morning, two rockets fired by Palestinian militants from the northern Gaza Strip hit the southern Israeli city of Sderot, slightly wounding one Israeli woman.

In response, the Israeli army shelled the suspected rocket launching sites in the Gaza Strip.

Israel's defense establishment on Tuesday accused Palestinian ruling Islamic Resistance Movement (Hamas) of directly involving in the Qassam attacks.

In response to the reported Hamas involvement in the rocket fire, Israeli Defense Minister Amir Peretz has threatened to "hunt down the Qassam gunners" and increase IDF retaliatory measures, according to Israeli newspaper Ha'aretz.

Peretz was also cited as saying that Israeli army would start targeting Hamas if it would not reign in its members who were behind the rocket attacks.
