The suspected attacker was captured and turned over to the police by witnesses to the assault, who told BuzzFeed News that he made his motivation for it clear by screaming, "I'm going to kill all Muslims!".
The footage obtained by LBC shows chaotic scenes after the terror attack, which targeted Muslims, that took place early on Monday morning. In the 50-second video, a group of bystanders can be seen dragging the suspect across the road while those who have been injured lay strewn around them. In March, a man drove a auto into pedestrians on Westminster Bridge and stabbed a police officer to death before being shot dead. A vehicle struck pedestrians near a mosque in north London early Monday morni.
Britain's terrorist alert has been set at "severe" meaning an attack is highly likely.
British Prime Minister Theresa May says she will chair an emergency session of the security Cabinet later Monday after a van crash in London that is being investigating as possible terrorism.
The deadly van-ramming attack at a mosque in London is "a painful illustration of why we must never allow hatred to breed hatred", Britain's chief rabbi said.
The driver of the van, a 48-year-old man, was found at the scene and detained by the public until police arrested him. He has been taken to a hospital as a precaution.
Basu said one man was pronounced dead at the scene but it was too early to confirm whether he was killed as a result of the terror attack.
Police said all victims of the attack were Muslim.
"This seems to be the latest and extremely violent manifestation of Islamophobia in Europe as we have been witnessing an increase in racist incidents and speech targeting Muslims across Europe", Michael Privot said.
Eight other people were taken to hospital, two of whom were seriously injured, he said. "I would urge everyone to remain calm and vigilant", Basu said.
Confirming an arrest has been made, Met Police commissioner Cressida Dick said: "London has woken up to the news of another appalling attack on our city".
In the aftermath of the attack, some observers suggested that anti-Muslim screeds in the British tabloids and on social networks could have incited the attacker to violence. Rahman said he and another man wrestled the suspect to the ground and held him down for 20 to 30 minutes before police arrived. "This person was conscious".
They also confirmed they were carrying out searches at a residential address in the Cardiff area in connection with the attack.
Mohammed Kozbar, the chairman of the mosque, condemned the "cowardly attack which is no different than the (terrorist) attacks in Manchester and London". The mosque called it a "callous terrorist attack".
