The Al Azaim Foundation, the outlet often responsible for spreading messages from ISIS, published a chilling poster with the message ‘Kill them all’ alongside the names of all four stadiums hosting the matches. “All matches are planned to go ahead as scheduled with appropriate security arrangements in place.”

The threat comes less than three weeks after Islamic State attacked the Crocus City Concert Hall in Moscow on March 22, when armed men stormed the building and fired guns at the audience.

Some 143 people died and around 200 were injured.
