Russian President Vladimir Putin said yesterday that the murder of Kremlin critic Boris Nemtsov was a shameful tragedy that carried a political subtext.

Nemtsov, a former deputy prime minister, was shot dead as he walked with his girlfriend on Friday night near Red Square. He was the most prominent opposition figure to be killed in Russia during Putin’s 15-year rule.

The Kremlin has denied any involvement, saying that the killing was a “provocation” designed to discredit Putin and strengthen his opponents, but Nemtsov’s friends say the Kremlin is to blame for fomenting an atmosphere of hatred towards its opponents.

“The most serious attention should be paid to high-profile crimes, including the ones with a political subtext. Russia should be devoid at last of the kind of shame and tragedies that we have recently endured and seen,” he said in a speech during a meeting with officials from the interior ministry.

“I mean the murder, the audacious murder of Boris Nemtsov right in the centre of the capital,” he said. Law enforcement officials have said one lead they were exploring was that the killing was linked to Nemtsov’s personal life or business dealings. Putin’s comments indicated that version is now being discarded.

Authorities have not made any arrests. Earlier on Wednesday, the director of Russia’s Federal Security Service said that an investigation had identified several suspects, without giving details.

Russian news agencies reported that investi­gators were seeking a car in connec-tion to the killing that may be connected to the finance ministry. The ministry said in a statement sent to Reuters that the car, a Ford, does not belong to the ministry itself but was owned by a state enterprise which provides security to government institutions, including the finance ministry.

The vehicle drove past the spot where Nemtsov was shot after the killing and when police patrol cars had already arrived at the scene, the statement said.
