An Israeli man was killed and four other people were wounded on Thursday when Palestinian militants in the Gaza Strip fired a mortar shell into Kibbutz Nir Oz in the western Negev.
Three of the casualties were moderately wounded and the fourth sustained minor wounds in the strike. All the victims were hit with shrapnel from the rocket.
After the strike, it emerged that the "Color Red" early warning system did not sound prior to the attack, and that the casualties were inside an unprotected building.
Magen David Adom emergency medical personnel said one of the victims was already dead when they arrived at the scene, and three other people had suffered shrapnel wounds to the chest and abdomen. One person was lightly hurt and was later treated for shock.
The militant Palestinian group Hamas claimed responsibility for the attack.
