A Qassam fired by Palestinian terrorist in north Gaza Saturday morning landed near an Israeli community located within the Sha'ar Hanegev Regional Council's limits. There were no reports of injury or damage.
The "Color Red" rocket alert was activated in the area shortly before the rocket exploded in an open area.
Earlier, another rocket fired from Gaza landed in Palestinian territory.
The rocket fire followed the death of 32-year-old Major Eliraz Peretz and 21-year-old Staff Sergeant Ilan Sviatkovsky in exchanges of fire with terrorists in Gaza on Friday, in what was the harshest incident for the Israeli army on the border with the Hamas-ruled territory since Operation Cast Lead.
An initial army investigation into the incident revealed that the terror cell was trying to plant explosive devices along the Gaza border fence set an ambush for the IDF troops, as Hamas claimed.
The soldiers, the army says, were hit during exchanges of fire and from the explosion of a grenade carried by Major Peretz.
"The decision by the IDF force to enter Gaza and chase after the terrorists was correct; this is what is expected of fighters in such an incident," a senior army official told Ynet late Friday.
However, the initial investigation revealed that some tactical mistakes were made by the IDF force after it entered Palestinian territory.
It is estimated that the army will retaliate with a wide-scale assault on Hamas targets in Gaza.
