Northumbria Police's chief constable has urged the public to "remain calm but alert" following a terror attack on the London Underground.
Prime Minister Theresa May yesterday announced that the UK's terror threat level had been raised to critical - meaning "an attack may be imminent".
More than 20 people were injured following the attack, which took place on Friday morning.
Today, Northumbria Police Chief Constable Steve Ashman said that there will be increased policing presence at key locations across the force area.
He continued: "This means the public will see more armed police officers at train stations, Metro stations, transport hubs and other high footfall locations.
"This increased security is to protect and reassure the public.
"The number of officers on duty, both armed and unarmed, has been increased significantly to provide a reassuring presence. This will remain in place for as long as is necessary.
"In some parts of the country the military may be deployed to provide visible protective security patrols, however there are no plans at this stage for the military to be deployed in the Northumbria area.
"There will be an increase in the numbers of armed police officers on patrol in our region to protect the public and that is being supported by police colleagues from the Civil Nuclear Constabulary.
"The safety and security of our communities remains our priority and we are working with partners, central government and other agencies across the country to keep the public safe.
"We will be reviewing security measures at events across the force area this weekend to ensure there is an appropriate policing presence.
"We would ask the public to remain calm but alert. If you see anything that causes you concern, report it immediately to the police."
