A mortar shell fired from Gaza exploded between two day-care centers in a southern Israeli kibbutz.
The shell landed Wednesday morning shortly before the children were supposed to arrive. Several teachers were in the buildings at the time of the attack.
There were no injuries, though one of the buildings reportedly sustained damage.
It was the third rocket fired from Gaza in the past three days. A Kassam rocket fired from Gaza struck Sderot at 2 a.m. Tuesday.
The attacks come following the start of direct peace negotiations between Israel and the Palestinians.
