A settler woman was killed Thursday when a homemade Qassam shell hit her home in the Brur Chail kibbutz in the Gaza Strip, an Israeli military source reported.

The woman was identified as Dana Glakowitz, 22 years old. She was seriously injured in the attack and died of her wounds shortly afterward, according to an Israeli medical source.

The shell was one of four fired from Beit Hanoun, in the northern Gaza Strip, the Israeli army reported.

Palestinian resistance fighters fired a total of 20 rockets and mortars at Gaza settlements and nearby Israeli towns, including the Negev town of Sderot and Nahal Oz settlement, according to the army. One police vehicle was damaged.

After the attacks, the settlers’ council released a statement demanding that Israeli Prime Minister Ariel Sharon stop the implementation of his disengagement plan.

In a separate incident, Israeli soldiers arrested three residents while they were trying to cross the fence which surrounds the Gaza Strip.

The army claims that the three residents were carrying grenades, and were transferred to Israeli security for interrogation.
