No group has yet claimed responsibility for the attack, though earlier in the month an ISIS affiliate group took credit for four rockets launched from the Sinai, a hotbed of terror insurgency, at the Israeli resort town of Eilat on the country's southernmost tip.
The rocket attack came a day after ISIS claimed that five members of its Sinai Peninsula branch were killed in an Israeli drone attack on Saturday night.
The February launches were the first time since 2015 that rockets had been fired at Israel from Egypt. "Forces are searching the area", said the IDF, reported the Guardian.
Police Officer Killed, Second Officer and Suspect Injured During Shooting in Whittier
One officer was killed and the other wounded while they were trying to help a man who had been in a traffic accident in Whittier. The suspected gunman was identified as Michael Christopher Mejia, 26, according to the Los Angeles County Sheriff's Department.
The rockets hit the Eshkol region, which borders southern Gaza and the northeastern tip of the Sinai Peninsula. Haaretz reports that a Palestinian man from Gaza, identiifed as Mohammed Id, was among those killed in the alleged Israeli strike. Three of the rockets were intercepted by the Iron Dome anti-missile system, while the fourth rocket exploded in an open area.
The images show a militant linked to the ISIS affiliate in Egypt, known as the Sinai Province, as he prepares two rockets prior to launching them from the restive Sinai Peninsula. It seems likely the same group is behind Monday's attack. Lieberman said that while IS in Sinai, know as Wiyalet, is "annoying" and "hindersome", it does not possess the means to pose a serious threat to Israel's security like terror groups Hamas or Hezbollah.
It wasn't immediately clear who fired the shells but Islamic militants in Egypt's lawless Sinai have been behind a number of such attacks in recent years.
