A Palestinian has rammed a truck into a group of Israeli soldiers visiting a popular tourist spot in Jerusalem, killing four and wounding at least 15 people, in a shocking copycat of the Berlin and Nice terror massacres.
Shocking video from the scene shows the driver reversing back over the soldiers, trapping ten under his wheels, during the sickening attack on Sunday.
Israeli Prime Minister Benjamin Netanyahu alleged the attacker 'supported' the Islamic State group, though he provided no details on what led to the finding.
Speaking at the scene of the attack, Mr Netanyahu said the attacker has been identified and 'according to all the signs he was a supporter of the Islamic State.'
He says there 'definitely could be a connection' between Sunday's attack, which killed four Israeli soldiers, and recent attacks in France and Germany.
The terrorist was shot dead by Israeli forces at the location overlooking holy sites in the Old City such as the Dome of the Rock and providing one of the most spectacular views of Jerusalem.
Chaos broke out at the scene when the truck ploughed through the crowd, with hundreds of soldiers having arrived there as part of a tour for troops about the history of Jerusalem.
'A lone terrorist drove his truck into a group of soldiers standing on the side of the road,' police spokesman Micky Rosenfeld told reporters at the scene.
'They got off the bus, and as they were getting off the bus and getting organised, he took advantage.'
Israel's military said one of its soldiers fired on the attacker and distributed video of him saying he shot after realising it was not an accident.
Multiple bullet holes could be seen in the windshield of the truck.
Police only confirmed four people were dead, but a medic at the scene said they were soldiers.
Medics also reported that three of the victims were women, while all four were in their 20s.
Netanyahu says Israel has blockaded Jabel Mukaber, the east Jerusalem neighborhood where the truck driver lived, and is planning other measures to prevent similar attacks.
The group of soliders were standing beside the bus on some grass when the truck bounced into the air onto the promenade and drove through the victims without warning.
The killer then stood on his brakes and reversed, trapping some ten of his victims under the truck.
Some of the surviving soldiers managed to jump clear and opened fire, riddling the cab of the truck killing the man.
The soldiers were on a cultural sightseeing tour of the city when they were attacked.
The atmosphere in Israel has also been charged following the manslaughter conviction last week of an Israeli soldier who fatally shot a Palestinian attacker who had already been badly wounded and was lying on the ground.
Eytan Rund, a tour guide who said he shot the attacker Sunday, said soldiers in the area were slow to respond. He said he believed the 'hesitation' was connected to last week's verdict.
Rund said: 'The truck sent me flying, I was lucky, just a couple of bruises. The right corner of the truck hit me and sent me flying, a couple of flips on the grass, I am quite amazed that I am standing here right now.
'The second biggest miracle is that my gun wasn't lost from this.'
He said he realised that attack was intentional after the truck 'suddenly turned around to probably run over again'.
'I pulled out the gun I fired one shot at the wheels and I realised this will not do and while he [the attacker] was driving I ran to overtake him from his left side, I stood in front of him and started shooting my entire magazine until it was over.
'He kept on driving after... I don't know if my bullets were the one that wounded him and made him stop, but without a doubt he kept on going a few metres after I shot him.'
It is understood soldiers fired at least 18 rounds at the terrorist, who is believed to be from an Arab area of east Jerusalem.
Tour guide Lea Schreiber said: 'I heard my soldiers screaming and shouting.
'I saw a truck that went on the side of the road. Soldiers starting shooting. There were orders and screaming everywhere. They told them to hide behind the wall because there was fear of another attack.
'There was no sense in that reverse. He drove backward to crush more people. That was really clear.'
The Palestinian Hamas movement praised the attack, but did not take responsibility.
Hamas spokesman Abdul-Latif Qanou called it a 'heroic' act and encouraged other Palestinians to do the same and 'escalate the resistance.'
Qanou said Sunday's attack proves the wave of Palestinian violence has not ended, despite a recent lull. He says 'it may be quiet, it may linger, but it will never end.'
Hamas, which rules the Gaza Strip, is pledged to Israel's destruction.
Jerusalem Mayor Nir Barkat called on residents to be wary but carry on with their everyday life.
'Unfortunately, there is no limit to the cruelty of terrorists who spare no means in killing Jews and disrupting their way of life. Those who incite and support terror must pay a heavy price.'
Police spokeswoman Luba Samri says the truck veered off course Sunday and struck a group of soldiers who had just disembarked from a bus.
Palestinian security officials in the West Bank city of Ramallah said he was a Palestinian from the east Jerusalem neighbourhood of Jabal Mukaber, close to the scene.
