Earlier in February, the Islamic State fired rockets at the southern Israeli town of Eliat.
The rocket fire followed the group's claims that an alleged Israeli drone strike killed five of its militants in the jihadists' Egyptian holdout. No one was injured and no damage was caused by the missiles, the army said.
In a statement on social media, the group said it had fired two Katyusha rockets at "southern Palestine", according to the Walla news site.
Israeli defense minister Avigdor Lieberman on Monday downplayed the threat posed by the group, saying that while they are "annoying" and "hindersome" they are not a serious concern for Israel's security.
The rockets hit the Eshkol region, which borders southern Gaza and the northeastern tip of the Sinai Peninsula.

"Like always, the special forces of Lichtenstein probably took out a few terrorists from Daesh in Sinai", Lieberman joked, using the Arabic name for the Islamic State.
"We do not let anything go without a response", he added. The Code Red alarm did not sound since the rockets were not heading to populated areas.
Egypt is waging a military campaign against Islamist extremist militants in the Sinai, who have attacked Egyptian civilians and soldiers. The fourth rocket landed in an open field.
