JERUSALEM, June 6 (Xinhua) -- Israel's defense establishment on Tuesday accused Palestinian Islamic Resistance Movement (Hamas) of directly involving in the Qassam attacks on Israel's southern city of Sderot earlier in the day, which lightly wounded a woman.

    The defense establishment has received intelligence indicating that Tuesday's attacks were perpetrated by Hamas, which since a 2005 ceasefire announcement had mostly abstained from direct involvement in terror attacks, local newspaper the Jerusalem Post quoted concerned officials as saying.

    Another daily newspaper Ha'aretz also reported that 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.

    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.

    Recently, Sderot has been a frequent target of rocket attacks launched by Palestinian militants in Gaza.

    On Monday, two rockets hit Sderot and two others landed outside the town, causing neither injury nor damage.

    Last week, one of four rockets fired from the northern Gaza Strip hit and badly damaged a residential building not far away from Israeli Defense Minister Peretz's house in Sderot.

    Roughly three weeks ago, a rocket scored a direct hit on a classroom in a Sderot high school, but nobody was hurt in the attack. Enditem
