The chairman of the attorneys chamber in Russia's Udmurtia region, Dmitry Talantov, has been detained after he criticized the government and military forces over a deadly strike on a shopping mall in the Ukrainian city of Kremenchuk.
Talantov wrote on Facebook that he was detained on June 28 and taken handcuffed to the Investigative Committee for questioning.
The Society of Russian Lawyers wrote on Telegram that Talantov was detained as he was trying to fly to Moscow.
No official reason has been given for Talantov's detention.
On June 27, when news of the deadly missile attack broke, Talantov condemned the strike, calling the Russian authorities "scumbags."
Talantov also is the lawyer for Ivan Safronov, a prominent former Russian journalist who is on trial in Moscow on a high-treason charge widely considered to be politically motivated.
At least 18 people died in the missile strike in Kremenchuk, which leaders of the Group of Seven (G7) called "a war crime."
Russia has denied it targeted the mall, saying it launched a "high-precision strike" on a nearby munitions depot and that subsequent explosions from the attack sparked the blaze at the shopping center.
