British holidaymakers heading to Spain have been warned the country's terror threat level has been raised to 'severe'.
Police patrols have been stepped up in the European country, as well as its islands.
A warning on the government website says terrorists are 'likely to try to carry out attacks in Spain'.
The terror threat level has been raised to four out of five.
The country is a popular holiday destination for Mancunian tourists, who flock to Barcelona, Madrid and the Costa del Sol each year.
The post, on the foreign travel advice section of the website says: "Attacks could be indiscriminate, including in places visited by foreigners.
"The Spanish authorities take measures to protect visitors, but you should be vigilant and follow the instructions of the local authorities."
Barcelona suffered a terrorist attack in August, 2017, in which 16 people died. A total of 130 others were injured.
The website continued: "Spanish police have disrupted a number of groups suspected of recruiting individuals to travel to Syria and Iraq from 2015 to the present date.
"Some of them expressed an intention to carry out attacks in Europe.
"There’s a heightened threat of terrorist attack globally against UK interests and British nationals from groups or individuals motivated by the conflict in Iraq and Syria. You should be vigilant at this time."
The Daily Star online said that up to 40,000 more Spanish police will be deployed to tourist hotspots across the country.
Police will be visible outside stations, beaches, hotels and restaurants as part of Operation Summer.
The aim of Operation Summer is to “take full action to obtain information in order to prevent terrorist acts” while also “reinforcing security measures at events and places that will attract a large number of people”.
