Outrage as step-by-step manuals teaching lone-wolf terrorists how to use vehicles to ‘crush victims’ are STILL on Google and Twitter after London terror attack
Boris Johnson has now demanded social media companies do more to take down “corrupting” hate sermons posted online
SICK internet guides telling 'lone wolf' extremists exactly how to carry out car terror attacks were still available on Google and Twitter on Thursday night.
The news comes just hours after the Westminster Bridge atrocity and as experts warned Brit-based jihadis are using them for training.
In the horrific online guides, fanatics are urged to use large vehicles as terrifying ‘tools of war’ before going on murderous stabbing rampages.
The instructions bear a chilling similarity to the Westminster Bridge atrocity which left five dead.
Attacker Khalid Masood was among those who died on Wednesday.
Masood, who was shot down by police, mowed down pedestrians long a pavement in Westminster before stabbing a cop to death in the grounds of Parliament.
Boris Johnson has now demanded social media companies do more to take down “corrupting” hate sermons posted online to curb radicalisation.
The Foreign Secretary warned that “polluting” messages were circulating across the internet and that firms had to act quicker to take them offline.
He said the fight to defeat Isis must win over people’s “hearts and minds” as well as “crushing” the jihadists on the battlefield.
"This is something that the internet companies and social media companies need to think about," he said.
"They need to do more to take that stuff off their media, the incitements, the information about how to become a terrorist, the radicalising sermons and messages. That needs to come down."
Just hours after the attack The Sun found evil terror manuals on Twitter.
One had a section on the best vehicles to use in a terror attack while another advised on the best knife to buy for a street execution.
It also had tips on how to choose a random victims off the street.
Another manual was written in the wake of the Bastille Day attack in Nice which claimed the lives of 86 people including ten children and teens.
It said the Nice attack “superbly demonstrated” how vehicles can be used for terror, having the effect of “smashing their bodies while crushing their heads, torsos and limbs under the vehicle’s wheels leaving behind a trail of carnage”.

“It has been shown that smaller vehicles are incapable of granting the level of carnage that is sought. One of the main reasons for this is smaller vehicles lack the weight and wheel span required for crushing many victims.
“The type of vehicle most appropriate for such an operation is a large load-bearing truck.”
Twitter said that in the last six months of 2016 it suspended 376,890 accounts for violations related to promotion of terrorism.
A spokesman added: “We don’t comment on individual accounts for privacy and security reasons.”
Police are now looking into whether Muslim convert Masood was radicalised online.
The Sun online has already revealed how Isis published a terror manual teaching lone-wolf jihadis how to use lorries as weapons to “crush many victims” in Berlin and Nice-style attacks.
The sick step-by-step guide, released last month in the terror group’s Rumiyah magazine, said using a vehicle was one of the most lethal methods of attack.
An “idiot's pre-attack checklist” even warned terrorists to “check the vehicle has enough petrol” and suggested "low security” gatherings as “desirable” targets.
It is thought the ‘Terror Tactics’ manual may have inspired the Berlin Christmas market attack on Monday night which claimed 12 lives and injured 48 others.
Isis has claimed responsibility for the attack and praised the terrorist behind the massacre as a “soldier”.
The horrific slaughter came just weeks after the terror manual encouraged extremists to plough trucks and cars into crowded outdoor events.
Outdoor markets, political rallies and “any outdoor activity that draws large crowds” were listed as “excellent targets”.
The chilling four-page manual said lorries had large enough wheels for "smashing their bodies while crushing their heads, torsos and limbs" and "leaving a trail of carnage".
After the attack in Berlin, ISIS called for lone wolves to smash cars and lorries into groups of "unbelievers" at Christmas markets across the globe.
The Sun Online revealed how Islamic State’s bloody-thirsty Abu Mohammad al-Adnani is still inspiring horrific atrocities across Europe from beyond the grave a year after he was killed.
The ISIS propaganda chief’s murderous rants calling for murdering civilians in western cities are still being listened to by legions of fanatics bitter about the so-called caliphate crumbling to dust.
