JERUSALEM, Israel - Palestinian terrorists in the Gaza Strip fired four mortar shells into southern Israel on Tuesday.

One shell exploded in a parking lot in the Sha'ar Hanegev Regional Council, damaging one car. Another mortar damaged an irrigation hose in a nearby field.

The color red air raid siren sounded moments before the mortars hit. A few hours later, the siren sounded again as more shells exploded in the area. There were no injuries in either attack.

Islamic Jihad's "military" wing, the al-Quds Brigades, claimed responsibility for the attacks. According to their announcement, the mortar shells were aimed at an Israeli Defense Forces post east of the Gaza Strip.

Last week, Palestinians fired a longer-range Grad-type rocket at the city of Netivot, which landed near a wedding hall where a reception was taking place. The rocket damaged a park car and a paved road. Four people were treated for shock.
