The Spanish government warn that threats have also reportedly been made against their country by ISIS over social media.
A new report from the Government claims that the terror group is also recruiting translators and foreign jihadists from the county.
According to the Express, the document also claims that the terror group have been publishing in Spanish - thus "increasing the risk of its influence on radicals living in our country".
The news will come as a stark warning to the millions of Britons who spend their summers in Spain with ISIS reportedly vowing to take revenge on the country.

Counter-terrorism forces in Spain have warned about an "increase in allusions to our country" in worrying propaganda issued by ISIS.
Propaganda videos, subtitled in Spanish and aimed at possible recruits in Spain, have also increased following the arrests of dozens of suspected militants in 2016.
Fears of another attack on holidaymakers have been increased since the devastating Tunisia massacre in June 2015, killing 30 British tourists.
ISIS have also claimed responsibility for killing thousands of people in attacks on Paris, a Christmas market in Berlin and the Bastille Day fireworks in Nice last year.
Both Spain and the UK are currently at level four on the anti-terror alert.
