A "code red" siren sounded in the Hof Ashkelon area Friday afternoon, in Yad Mordechai and Netiv Ha'Esrai.
The IDF has now stated that the alarm is a false alarm, and that there were no hits, injuries, or damage.
The alarm follows an attack last Friday, whereby a Qassam rocket was launched from Gaza into Kibbutz Nir Yitzhak.
Friday's attack - which thankfully did not result in any injuries - was the third such rocket attack since the August ceasefire with Gaza, and provoked a retaliatory strike by the Israeli Air Force.
The perpetrators of that attack are believed to be among the smaller Islamist and far-left splinter groups in Gaza, but Israel holds the Islamist terror group responsible for all attacks into Israeli territory given that it is Gaza's de-facto rulers.
