ISIS Video Calls for Attacks in Europe, US During Ramadan

An Islamic State spokesman is calling on Muslims to wage jihad ("holy" war) in Europe and the United States during Ramadan if they are unable to join the caliphate in Iraq and Syria.

"Ramadan, the month of conquest and jihad," the spokesman says in the 30-minute video. "Get prepared, be ready…to make it a month of calamity everywhere for the nonbelievers…especially for the fighters and supporters of the caliphate in Europe and America."

"The tiniest action you do in their heartland is better and more enduring to us than what you would if you were with us," the spokesman continues. "If one of you hoped to reach the Islamic State, we wish we were in your place to punish the crusaders day and night."

The narrator also encourages so-called "lone wolf" attacks during Islam's holy month of Ramadan, which begins Sunday, June 5.
