The popular video-sharing website YouTube has been partially blocked in Tajikistan.
Asomuddin Atoev, the chairman of Tajikistan's Association of Internet Service Providers, told RFE/RL that YouTube stopped being accessible via several Internet providers as of June 9.
Atoev said the Tajik government's Communications Service might have requested that some Internet providers block YouTube.
However, the chief of the Communications Service, Beg Zuhurov, told RFE/RL that his agency had nothing to do with the situation.
The reason for the blockage is not known.
In the past few years, Tajik authorities have blocked several online news and social-media websites, including RFE/RL's Tajik Service and Facebook, but later unblocked them.
At the time, Zuhurov blamed the disruptions on "technical problems."
