Tamerlan and Dzhokhar Tsarnaev, the suspected Boston bombers who led police on a wild shootout Thursday night, are of Chechen background. The 19-year-old Dzhokhar, who remains at large after his brother died, was born in the central Asian nation of Kyrgyzstan.
Chechnya has long inspired violent struggle. In the 1990s and early 2000’s, Chechens waged a bitter fight for independence from Russia, followed by a brutal crackdown led by Vladimir Putin’s regime. Over the last decade, Chechen separatists fighting against Russia have developed operational and ideological ties with Islamic extremist groups—most prominently in Afghanistan, where they’ve flocked to aid the anti-U.S. insurgency, experts said.
In recent years, Chechens were “the most significant non-Afghan element of the insurgency,” in Afghanistan, said Sarah Chayes. Chayes, a senior associate at the Carnegie Endowment for Peace, spent several years in Afghanistan. “It was an absolutely constant element of the insurgency,” she told msnbc.
Since the Chechen uprising in the 1990s, Russia has cracked down on the region, stifling political dissent. That has led some Chechen Muslims to travel farther afield in search of causes, Chayes explained.
“You have a horrific crackdown that makes it very difficult for people to function in their own environment,” she said. “Some of the most radical fringes have sort of broken off from the larger Islamist movements within their countries”—including other central Asian nations like Uzbekistan—“and become attached to this more internationalist global jihad,” she said.
In other words, that nationalist cause appears to have served as a gateway for some Chechens into the radical Islamic movement—turning the U.S. into a potential target.
“These links have gone on for some time, since the 90s,” Roger Kangsas, a dean at the Near East South Asia Center for Strategic Studies, told msnbc.
Still, the brothers appear to have come to the U.S. as kids, and to have been relatively assimilated into American life. In 2011, Dzhokhar was awarded a prestigious scholarship by the city of Cambridge, Mass, and Tamerlan once boxed in a Golden Gloves charity program.
