Sunday’s attack was one of the deadliest clashes between militants and the Tajik government since the Central Asian country’s civil war ended in 1997. The last comparable attack was in 1998, when militants ambushed a battalion of Interior Ministry troops just outside Dushanbe, killing 20 and kidnapping 110. Sunday’s incident was preceded by a Sept. 3 attack on a police station that involved a suicide operative and a vehicle-borne improvised explosive device (VBIED) in the northwest Tajik city of Khujand that killed four police officers. Suicide attacks are rare in Tajikistan, and VBIEDs even more so. The Khujand attack also stands out as it occurred outside militant territory. Khujand, Tajikistan’s second-largest city after the capital, is located at the mouth of the Fergana Valley, the largest population center in Central Asia.

This represents a noticeable increase in the number and professionalism of militant operations in Tajikistan. Regardless of whether the September attacks can be directly linked to the Aug. 24 jailbreak in Dushanbe, the sudden re-emergence of attacks in Tajikistan after a decade of quiet in Central Asia deserves our attention. In short, something is percolating in the valleys of Central Asia that has reawakened militant groups more or less dormant for a decade. This unrest will likely continue and possibly grow if Tajik security forces can’t get control of the situation.
