Visitors to Tajikistan should exercise increased caution, according to the State Department, which warns of potential terrorism threats in the region from organizations such as ISIS. "Most recently, on November 6, 2019, there was a deadly attack at a border post in Rudaki district, on the Tajikistan-Uzbekistan border," the update states. "Last year, on July 29, 2018, U.S. citizens were targeted in a terrorist attack in Danghara while bicycling in the central region of the country. ISIS has claimed responsibility for both attacks."
