Armed police in England and Wales have been given training on how to tackle terrorists who are driving trucks - and told to shoot anyone who poses a major threat.
The tactics have changed after last year's terror attacks in Nice and Berlin, which accounted for almost 100 lives between them.
Simon Chesterman, the National Police Chief Council's lead on armed policing, was quoted by Sputnik as saying that officers had previously been instructed not to shoot drivers in case they lost control of the vehicle.
Now, however, armed officers have been told they should shoot at drivers who pose a threat to others.
Chesterman said: "If the vehicle is being used as a weapon in the first place there aren't many tactics available in relation to stopping it, especially if it is a very large lorry.
"So driving a vehicle in front of it, for example, is not going to stop it, so you need to shoot the driver."
Chesterman also said that the Government has spent £143 million on training firearms officers to a much higher standard, since the terror attacks in Paris in 2015.
He also explained that there will soon be 7,000 firearms officers in Britain, a figure which includes counter-terrorism specialist firearms officers.
These officers are highly trained and, if needed, can rappel out of helicopters.
