Islamic State has urged its followers to attack citizens of the United States, France and other allies who have joined a coalition to fight the militant group, the SITE monitoring website said on Monday.
The United States is building an international coalition to destroy the radical Sunni Muslim group, which has seized swathes of territory in Iraq and Syria and proclaimed a caliphate in the heart of the Middle East.
U.S. and French warplanes have struck Islamic State targets in Iraq and on Sunday the United States said other countries had indicated a willingness to join it if it goes ahead with air strikes against the group in Syria too.
Islamic State spokesman Abu Muhammad al-Adnani said the military intervention by the U.S.-led coalition would be the “final campaign of the crusaders”, according to a transcript published by SITE.
“It will be broken and defeated, just as all your previous campaigns were broken and defeated,” he said in the statement, which urged followers to attack U.S., French, Canadian, Australian and other nationals.
