Police have launched an awareness campaign in a bid to make it harder for terrorists to attack the UK.
The North East Counter Terrorism Unit (NE CTU), which West Yorkshire Police has responsibility for, is supporting the initiative.
The National Counter Terrorism Awareness Week runs from today.
During this week police and partner agencies will deliver activities and events across the country.
This are aimed at increasing vigilance amongst the general public, business and transport community.
Each day will feature a different theme.
These are crowded places, transport hubs, preventing violent extremism, terrorist financing and the tools terrorists need to operate.
These will be supported through activities ranging from security briefings to public advice in community venues, universities and shopping centres.
Targeted police operations will also take place at key sites across the region.
These are aimed at disrupting terrorist activity, or criminal efforts which may help to fund or support terrorist objectives.
The NE CTU is one of five counter terrorism units designed to strengthen the UK’s response to the threat of terrorism.
Assistant chief constable Geoff Dodd, the lead for the NE CTU, said: “In August the threat to the UK from International Terrorism was increased to Severe.
“While there is currently no specific intelligence of an attack on the UK, it is vital we ensure we are in the best possible position to prevent and detect any potential terrorist threats.
“Members of the public and the business community have a particularly important role to play when it comes to recognising suspicious activity and reporting it to police.
“Those who work in, or visit, crowded places are often best placed to recognise the early signs that something is wrong.
“We want them to know what to do if they suspect something is out of the ordinary and how they can help to protect themselves and others.”
Mr Dodd added that by working together communities can make it harder for terrorists to operate.
He added: “Through increased awareness and vigilance we can reduce their opportunities and disrupt their activities to better protect our communities, our businesses and industry.”
Anyone with concerns about suspicious activity or behaviour is asked to contact the Confidential Anti-Terrorist Hotline on 0800 789 321.
