Two men have been detained over the murder of Russian opposition politician Boris Nemtsov, the head of the Federal Security Service (FSB) has announced. Anzor Gubashev and Zaur Dadayev were detained on Saturday, FSB director Alexander Bortnikov said, speaking on national television. He told other Russian media that both men were from the Caucasus. The murder last month of the veteran liberal politician, on a bridge within sight of the Kremlin, shocked Russia. The former deputy prime minister, 55, was shot in the back four times on the night of 27 February as he was walking on the street with his girlfriend. He was buried in Moscow on Tuesday. That the announcement was made on state television by the head of the FSB himself is a clear sign the Kremlin wants to be seen taking this case extremely seriously, the BBC's Sarah Rainsford reports from Moscow. 'Car found' Mr Bortnikov gave no details of how and where the suspects were detained, in the brief statement carried by Russia's state-owned Channel One, but he did say the investigation was continuing. Neither of the men has yet been charged but a source said to be familiar with the investigation told Russia's Interfax news agency they were suspected of carrying out the killing. The car they allegedly used was found rapidly and evidence gathered in the vehicle was used along with phone records to identify the suspects, the source said. Footage from security cameras had provided "sufficiently clear" images of the suspects, he added. President Putin has publicly condemned the murder and called for an end to "shameful" political killings in Russia. But leading opposition figure Alexei Navalny accused the Kremlin of ordering the assassination in order to cow the opposition amid Russia's mounting economic problems. Russian investigators have publicly offered multiple motives ranging from Nemtsov's business dealings to his condemnation of the Charlie Hebdo attack in Paris. Nemtsov was killed just days before a march he was organising against the war in Ukraine. He had also been drafting a report expected to expose covert Russian military involvement in the conflict. Some 50,000 people attended a rally near the Kremlin in protest at his death on 1 March and thousands turned out to pay their respects on the day of his funeral. One Russian MP, Nikolai Kovalyov, told Ria-Novosti news agency that the key thing was to "find out who ordered this assassination". Opposition activist Ilya Yashin said it was not enough to establish that the suspects had killed Nemtsov. Writing on Facebook (in Russian), he said investigators needed to identify and arrest the organisers of the murder. "If those who ordered the murder are able to escape responsibility, the practice of political murders will definitely go on," he said. Source: BBC
