ISIS issue terrorist attack threat on Arsenal vs Bayern Munich Champions League clash

ISIS have issued a threat to target all four Champions League quarter-final matches this week, including Arsenal's home game with Bayern Munich at the Emirates Stadium.

Arsenal will take on the German champions in the first leg of the quarter-final match tonight in north London. But there will now be concerns over safety after the Al Azaim Foundation, a mouthpiece for ISIS, issued a chilling poster with the message 'Kill them all' alongside the names of all four stadiums hosting the matches.

This has led to increased security measures in the Spanish capital, where two of the games will take place. Real Madrid take on Manchester City tonight, with Atletico Madrid hosting Borussia Dortmund on Wednesday.

The threat emerges less than three weeks after the Islamic State launched an attack on Moscow's Crocus City Concert Hall on March 22, where armed assailants stormed the venue and opened fire on the crowd. The horrific incident resulted in the death of 143 people and left around 200 injured.

Just a week later, ISIS-affiliated media outlet Sarh al-Khilafah released an image inciting an attack on Bayern Munich's Allianz Arena during the Bundesliga face-off between Bayern and Borussia Dortmund. Thankfully, the match proceeded without any incidents following heightened security measures around the stadium.

Spanish police have heightened security ahead of Real Madrid's clash with Manchester City. Spanish authorities have stated that «in terms of preventing the terrorist threat, the State Security Forces and Bodies have activated all their early warning and protection systems, as well as all their response mechanisms ready and willing».
