MOSCOW (Sputnik) — According to Brennan, all anti-Daesh efforts made by Washington and its allies have not reduced the "terrorism capability and global reach" of Daesh.
"ISIL [IS] has a large cadre of Western fighters who could potentially serve as operatives for attacks in the West. And the group is probably exploring a variety of means for infiltrating operatives into the West, including refugee flows, smuggling routes, and legitimate methods of travel," the statement published on the Senate's website quoted Brennan as saying.
Daesh, which is banned in the United States, Russia and several other countries, claimed responsibility for the terrorist attacks in Paris on November 13, which killed 130 people, and the March 22 series of blasts in Brussels, which claimed the lives of 35 people.
A US-led coalition of over 60 nations has been conducting airstrikes against Daesh in Iraq and Syria since 2014.
