British tourists have been warned to be "vigilant" as Spain's terror threat is raised to "severe".
According to the British Foreign Office, terrorists are likely to carry out attacks in Spain, including in places visited by tourists.
Popular destinations such as Benidorm, Barcelona and Madrid have all been threatened by ISIS, Birmingham Mail reports.
The country's terror threat level has now been bumped up to four out of five.
Police patrols have reportedly been stepped up across Spain, as well as its islands.
The government's travel advice for Spain on the Foreign Office website reads: "Terrorists are likely to try to carry out attacks in Spain. 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.
"On 17/18 August 2017, there were 2 terrorist-related incidents where vehicles were driven directly at pedestrians, resulting in injuries and loss of life. These were in the Las Ramblas area of Barcelona and Cambrils, near Salou (100km southwest of Barcelona)."
It adds: "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."
