All three attackers were ultimately shot dead by border guards.
For several months during 2015, these knife attacks by Palestinian teenagers on Israelis were becoming fairly common. It was feared that the number of attacks would grow.
Palestinian media named the attackers as Adel Ankush, 18, from a village near Ramallah, Bra'a Salah, 18, from the same village, and Amar Bedui, 31 from Hebron.
Israel accuses the Palestinian establishment of inciting the violence, including by glorifying attackers and supporting their families.
The soldiers warned that they will shoot and kill any Palestinian who is seen walking outside at night, and that the siege will continue until further notice.
In a series of freakish twists, different terrorist groups are competing for the honor of taking credit for killing Hadas Malka.
A statement issued by its Amaq news agency said: "Let the Jews expect the demise of their entity at the hands of the Caliphate soldiers".
In its statement, IS said the attack was "revenge for the religion of Allah and the sanctities of the violated Muslims". The names differ from those reported by ISIS. They banned the Palestinians from entering and exiting the Old City and obliged the commercial stores' owners to shut down otherwise they would pay a fine of over NIS 40,000.
Israeli police also said that no connection has been found between the three Palestinians who carried out the attack in Jerusalem and any organisation.
The Israeli police relaxed its open-fire regulations in December 2015, permitting officers to fire, with live ammunition, on those suspected of throwing stones or firebombs as an initial option, without having to use non-lethal weapons first.
At his weekly Cabinet meeting, Netanyahu lashed out at Palestinian leader Mahmoud Abbas for not condemning the attack.
All of these statements are pure public relations statements. This is cause for concern and shows the younger group of Palestine Arabs are getting increasingly radicalised. Each group is hoping that they can feel the love from the generation of Palestinian kids, but that's not going to happen.
"The idea that this was some kind of a coordinated event, potentially, with multiple attackers is less frequent", Al Jazeera's Harry Fawcett, reporting from occupied East Jerusalem, said.
Earlier this year, Islamic State claimed it had launched a rocket attack from Egypt's Sinai Peninsula into Israel. In so doing, the Globe turned Palestinian terrorists into victims.
