Islamic State 'threatens terrorist attack on Champions League games', vowing to attack the Parc des Princes, Santiago Bernabeu, Metropolitan and Emirates Stadium, with a message reading 'kill them all'

Terrorist group Islamic State have threatened to launch an attack against the four stadiums hosting the first leg of the quarterfinals of the Champions League.

The Al Azaim Foundation, a media outlet that is responsible for spreading messages from the Islamic State (Daesh, ISIS), confirmed their intentions with a poster on Monday morning.

The foundation shared an image threatening to attack the Parc des Princes, the Santiago Bernabeu, the Metropolitan and the Emirates Stadium, with a message reading: 'Kill them all'.

The threat came shortly after the ISIS-affiliated media outlet Sarh al-Khilafah announced their plan to attack the fans who were at the Allianz Arena in Munich to watch the match between Bayern Munich and Borussia Dortmund.

The Champions League fixtures scheduled to take place at the Parc des Princes, Santiago Bernabeu, Metropolitan and the Emirates Stadium are due to take place this week.

According to AS, the Spanish Government have activated their security procedures for the Champions League double-header this week. It's believed more than 3,000 members of security have been assigned to the fixtures in Spain - Real Madrid vs Manchester City and Atletico vs Borussia Dortmund. 

It is also believed over 8,000 Manchester City and Borussia Dortmund fans will travel to Spain for the fixtures due to take place on Tuesday and Wednesday evening. 

The Islamic State's last attack took place on March 22 at the Crocus City Hall - which is a large concert hall in Moscow.

Several men stormed the building, dressed in camouflage and killed 143 people. They wounded a further 200 people.
