The Islamic State (ISIS) is likely to next launch terror attacks in Russia and "ultimately, the United States,"
Breitbart reports.
An Arab intelligence official told the news service the belief is based on the interrogations of "hundreds of militants" arrested in Syria, Iraq, Lebanon, Turkey and Europe.
Earlier this week, two ISIS operatives bombed an airport and train station in Brussels killing 31 — including two Americans — and injuring 270. The assault has put the European Union on high alert for possible further violence.
"The information that we have collected tells us that the organization is bent on carrying out a massive attack in Russia," the source tells Breitbart's Jerusalem bureau.
"Many of the detainees said they are aware of Chechen jihadis who trained in Syria and Iraq in preparation for striking Russia."
The United States, according to the source, is also said to be on ISIS' radar.
"ISIS tries equally hard to carry out an attack in the United States, but it would require greater efforts than in Europe," the source told Breitbart.
