Two Israeli men, one in his 40s and the other in his 20s, died of their wounds Saturday night after being stabbed in Jerusalem’s Old City in a terror attack.

The younger man’s wife was in serious condition and their two-year-old baby was lightly wounded. The mother was taken to Hadassah Hospital Ein Kerem and was undergoing surgery. The toddler was taken to Shaare Zedek Medical Center for treatment where he remained in stable condition.

The men were stabbed in the upper body and were unconscious when paramedics arrived at the scene.

The father was taken to Hadassah Hospital Mount Scopus where he died of his wounds shortly after the attack. The second man was taken to Shaare Zedek Medical Center where he also died Saturday night.

When the attack began, the injured woman managed to run and alert a group of Border Police forces nearby who arrived on the scene and shot and killed the attacker.

In video footage that emerged Saturday night after the attack, a woman’s screams can be heard followed by gunshots.

The baby was hurt in the leg, although it was not entirely clear how. Police said the attacker may have grabbed a firearm the father was carrying but it was not clear if he managed to fire it.

The incident occurred near Lion’s Gate in East Jerusalem.

The terrorist was identified as Muhannad Shafeq Halabi, 19, from al-Bireh, near Ramallah in the West Bank.

Palestinian Islamic Jihad claimed responsibility for the attack, while Hamas issued a statement praising the “heroic operation.”

“Halabi is a member of Islamic Jihad,” a senior member of the Palestinian terror group told AFP on condition of anonymity, after the group issued a statement hailing the attack and saying it was in response to Israeli “terrorist crimes” against Palestinians.

Saturday’s attack came just two days after an Israeli couple was gunned down in front of their four young children while driving in the West Bank on Thursday evening.

Naama and Eitam Henkin were shot dead by two Palestinian attackers while driving between the settlements of Elon Moreh and Itamar, near the Palestinian village of Beit Furik, close to Nablus.

Their children — aged 9,7, 4 and 4 months — who were in the backseat of the vehicle, were unharmed.
