MOSCOW — Five men were behind bars Sunday either charged or suspected in the killing of Kremlin critic Boris Nemtsov, but details remained unclear in the case that has shaken Russia’s marginalized and struggling opposition movement.
The five appeared in a Moscow court, where two of them were charged in connection with the shooting of Nemtsov as he walked across a bridge near the Kremlin on Feb. 27. The other three were remanded to jail pending the filing of charges, which Russian law says must be done within 10 days.
Russian news reports meanwhile cited unnamed sources as saying another suspect had killed himself with a grenade after police blocked his apartment on Saturday in Grozny, the capital of the republic of Chechnya. There was no official comment from Moscow on the reports, but Chechen President Ramzan Kadyrov appeared to partially confirm it Sunday.
One of the judges in the two separate hearings said suspect Zaur Dadaev had acknowledged involvement, but Dadaev did not admit guilt in the courtroom, according to state-run and independent news agencies in Russia. The other suspect who was charged, Anzor Gubashev, denied guilt, the reports said.
The three others include Gubashev’s younger brother Shagid, along with Khamzad Bakhaev and Tamerlan Eskerkhanov, state news agency Tass reported.
All five are from Chechnya or other parts of the restive North Caucasus, according to news agencies. Their origin raises a potentially sensitive issue, given the significant animosity for Caucasus groups among ethnic Russians.
Chechnya suffered two intense wars over the past two decades between Russian forces and separatist rebels increasingly under the sway of fundamentalist Islam. That reinforced the stereotype among many Russians of Chechens as violent extremists.
Kadyrov, the current Chechen president, has himself imposed many Islamic rules on Chechnya, including the wearing of headscarves by women, but is also a vehement loyalist of Russian President Vladimir Putin and has blamed Nemtsov’s killing on Western security services.
Kadyrov is widely criticized by human rights groups for violence against dissidents, including abducting and killing them. Dadaev, one of the suspects charged Sunday, had been an officer in the Chechen police troops, reports cited the head of the security council in neighboring Ingushetia as saying.
Kadyrov on Sunday said on Instagram that Dadaev had left the police troops under unclear circumstances. He described him as a “deeply religious man” offended by Nemtsov’s comments after the attack on the French satirical publication Charlie Hebdo. Russia’s Investigative Committee had suggested Islamic extremism as a possible motive for Nemtsov’s killing.
He also praised a man called Beslan Shavanov as a “brave warrior.” That was the name given in the unsourced reports of the suspect who allegedly killed himself in Grozny. Kadyrov’s post did not give details, but said Shavanov “perished the previous day during an attempt to detain him.”
Dadaev and the Gubashevs were arrested in Ingushetia on Saturday, and the other two suspects in suburban Moscow before dawn on Sunday, officials said.
Law enforcement officials have asserted the guilt of all five, but have not released any details of how they allegedly were involved in the killing of Nemtsov.
The 55-year-old Nemtsov, a former deputy prime minister who became one of Putin’s most outspoken detractors, was killed a few hours after he had made a radio appearance denouncing Putin for “mad, aggressive” policies in Ukraine.
Nemtsov was working on a report detailing Russian involvement in the war between pro-Russia separatist rebels and Ukrainian forces, associates said.
Nemtsov’s killing shocked Russia’s already beleaguered and marginalized opposition supporters. Suspicion in the opposition is high that the killing was ordered by the Kremlin.
But Russia’s top investigative body said it was considering several possible motives, including that he was killed in an attempt to smear Putin’s image. It also said it was looking into possible connections to Islamic extremism and Nemtsov’s personal life.
The opposition and others critical of the Russian leadership believe that Nemtsov’s death in a tightly secured area near the Kremlin wouldn’t have been possible without official involvement, and could be an attempt to scare other government foes.
Putin, who had dubbed Nemtsov’s killing a “provocation,” made no comment on the detentions announced Saturday.
