No casualties were reported following Saturday's rocket attack on the southern Israeli town of Sderot.
He identified the three dead as: Mahmoud Adel al-Walaidah, 24, Mohammed Farid Abu Namous, 27, and Mohammed Samir al-Taramsi, 26.
In a related development, Israel National News reported that three terrorists were killed attempting to infiltrate Israel from the Gaza Strip overnight Saturday, according to reports by Arab media sources.
In response to the attack, the spokesperson for the Hamas party, Fazi Barhoum, told reporters that this "Israeli strike is a message of escalation and aggression against the Gaza Strip in an attempt to steer attention from courageous acts by Palestinians in the West Bank, actions that have embarrassed Israel and caused embarrassment in the Israeli political arena".
The beginning of 2019 saw a dramatic increase in the level of violence along the Gaza border, with near nightly riots and airborne arson attacks, but the violence has waned in recent months due to a de facto ceasefire agreement between Israel and Hamas.
Blue and White Chairman Benny Gantz on Sunday toured the Israeli communities bordering the Gaza Strip and slammed Prime Minister Benjamin Netanyahu for failing to deal with the security issues facing southern Israel.
The incident came a day after Israeli jets struck two underground sites in the northern and central Gaza Strip.
On August 1, a Palestinian gunman fire shots at IDF forces, injuring three soldiers before he was eliminated.
During the attack on Saturday night, Palestinian terrorists in Gaza launched at least three rockets at Israel, with the Iron Dome shooting down two of them.
At least 305 Palestinians have been killed by Israeli fire in Gaza or the border area since then, the majority during demonstrations and clashes.
