Kyrgyz opposition politician Azimbek Beknazarov was detained on September 12 after the State Committee for National Security (UKMK) summoned him for questioning, his son told RFE/RL. Ruslan Beknazarov added that the reason of his father's detention is unknown. The UKMK has yet to officially announce the detention. Beknazarov, 68, was among 27 activists acquitted of charges of "calls for mass disorders" and "plotting the seizure of power" in a high-profile case related to a deal that saw Kyrgyzstan hand over a disputed reservoir to Uzbekistan last year.
