Israel Defense Forces (IDF) said it identified missiles launched from Iran toward Israel on Sunday and was activating its defensive systems to intercept the threat.

The Iran missile attack on Israel followed strikes carried out by the IDF this weekend on Iran-backed Hezbollah militant targets in southern Beirut, Lebanon.

The alleged missile attack aimed at Israel came just hours after Iranian lawmaker Ebrahim Rezaei promised a "decisive and painful response" to Israel’s airstrikes on southern Beirut on Sunday.

Rezaei, spokesman for the Security and Foreign Policy Committee of Iran’s Parliament, issued a statement on social media, threatening, "This rabid dog must be disciplined and put in its place. Look at the sky of the occupied territories tonight."

IDF sent out a precautionary directive to mobile phones of residents in the area targeted by Iran, asking them to act responsibly and follow instructions to save lives.

Upon receiving an alert, the public is being instructed to enter a protected space and remain there until further notice.

Israel Defense Forces (IDF) announced on Sunday that its Military Police Criminal Investigation Division has opened an investigation into why an Israeli soldier opened fire on a Palestinian family's car in the West Bank, killing a 7-month-old and injuring his parents.

The incident occurred on Friday during operational activity in the city of Hebron's Judea Brigade area, according to the IDF.

"Based on the findings of the preliminary examination, it was decided to open an investigation by the Military Police Criminal Investigation Division. Upon its conclusion, the findings will be transferred to the Military Advocate General’s Office," the IDF said in a statement on Sunday.

The Palestinian Health Ministry identified the baby as Sam Fahd Abu Haikal, adding that his parents were also injured when an Israeli soldier opened fire on their vehicle.

In its initial statement about the incident, the IDF said troops “perceived a vehicle accelerating toward them,” prompting one of the soldiers to fire at the vehicle.
