German state security fear Islamic terrorists will target this summer's Euros

German state security officials believe that a regional branch of Islamic State are set to target the European Championship in Germany this summer, according to reports.

This week saw an apparent threat by the terrorist group against stadiums hosting Champions League ties across Europe, with security ramped up in Paris - where Paris Saint-Germain were due to face Barcelona at Parc des Princes - Madrid, for Real Madrid's clash with Manchester City, and at the Emirates, where Arsenal were to play host to Bayern Munich.

All three ties went ahead without incident, but French authorities went as far as drafting in their elite counter-terrorism BRI (Research and Intervention Brigade) after a post was shared by the Al-Azaim Foundation, a media channel responsible for spreading messages from the ISIS-K branch of the terror group.

ISIS-K claimed responsibility for the deadly terror attack on Crocus City Hall in Moscow last month.

But tensions will again be ramped up ahead of this summer's flagship European competition after a second threat was published in the group's propaganda magazine.

As per BILD, the current issue of Voice of Khorasan contains a call to action for terrorist attacks, which German state officials believe are directed at the UEFA tournament.

The issue features a number of graphics, including one which shows a picture of terrorist holding a gun and dressed in camouflage aboard a German S-Bahn train or tram titled: 'Last call before exit'.

On the seat next to the militant, there is a box on a seat labelled for explosives, underneath a sign reading 'Welcome to Europe'.

Another shows a drone flying over the recently renovated Bernabeu and is captioned: 'If they constrict and oppress you on the ground, then strike them
