The moment brave unarmed police officers confronted the London Bridge terror attackers has been revealed in frightening new footage.
The terrorists can be seen carrying large knives and wearing what were later found to be fake suicide vests, just minutes before they were shot dead, bringing an end to their deadly rampage.
Police officer Sam Balfour, 25, told the inquest into the 2017 attacks, which killed eight people including two Australians, of the moment he came face-to-face with the terrorists.
'Three of them stood in a line, holding knives. One of them was sort of raising it above his head, they were shouting at us and straight away I drew my baton,' he said.
PC Bartek Tchorzewski, 36, who was also there, said: 'We were just thinking about stopping them.
'But to be honest nothing can prepare you for that. No briefings.'
The terrorists were lawfully killed by police, a jury has ruled.
The inquest finally ended with the verdict clearing the officers who gunned down the attackers less than 10 minutes after they began their rampage.
Khuram Butt, 27, Rachid Redouane, 30, and Youssef Zaghba, 22, ploughed a van into pedestrians on London Bridge before jumping out and stabbing people near Borough Market in the night on June 3.
The jury found the attackers 'ignored clear warning shouts' from the police, BBC reports.
It came after chief coroner Mark Lucraft QC directed them that the verdict was the only 'safe' conclusion.
Among the victims were Australians Sara Zelenak, 21, and Kirsty Boden.
Metropolitan Police Commissioner Cressida Dick paid tribute to the coroner and jurors who at times saw and heard 'extremely harrowing' evidence.
She praised the 'tremendous courage and professionalism' of officers.
'Faced with an appalling and confused scene, they acted calmly, quickly, decisively, and in accordance with their training,' she said in a statement.
'There is no greater responsibility for an officer than having to make the split-second decision whether or not to use lethal force.'
Ms Zelenak and Ms Boden were stabbed to death while heading towards the crashed van their killers had abandoned during the attacks.
Ms Zelenak, an au pair, had been walking down a nearby street with a friend when they heard the sound of the crash.
Unknown to her the three men had already started stabbing bystanders with 20cm ceramic kitchen knives.
'She was with a friend and the two of the them walked a little way back to see what had happened,' the coroner said in his opening remarks at the inquest.
'She was stabbed multiple times.'
Ms Boden, a South Australian nurse, heard the van crash while having dinner with two friends at the nearby Borough Bistro.
She she immediately went towards the crash, with the coroner explaining that she told her dinner companions she was going to see if anyone was hurt.
But Ms Boden encountered Redouane and Zaghba running in the other direction and was stabbed to death, Mr Lucraft said.
Redouane then ran off but Zaghba continued to stab Ms Boden.
Canadian Christine Archibald, 30, Briton James McMullan, 32, Frenchmen Xavier Thomas, 45, Alexandre Pigeard, 26, and Sebastien Belanger, 36, and 39-year-old Spaniard Ignacio Echeverria also died in the attack.
