Russia Khodorkovsky: Court orders exiled tycoon's arrest
A Russian court has placed ex-oil tycoon Mikhail Khodorkovsky on an international wanted list over the 1990s murder of a Siberian mayor.
Mr Khodorkovsky has been living in exile in Europe since he was pardoned by President Vladimir Putin in 2013 after 10 years in jail for fraud.
He told the BBC he was considering applying for political asylum in Britain as one of several options.
Russia's once-richest man said the authorities had "gone mad".
Mr Khodorkovsky is accused of ordering several of his employees to kill both the mayor and a businessman, who survived.
Investigators allege Vladimir Petukhov, the mayor of Nefteyugansk, was killed on 26 June 1998 for demanding Mr Khodorkovsky's oil firm, Yukos, pay taxes that the company had been avoiding.
Local businessman Yevgeny Rybin was allegedly targeted because his activities "clashed with Yukos's interests", Russia's powerful Investigative Committee (SK) said in a statement (in Russian) as it announced his arrest in absentia.
Mr Rybin survived a gun attack in November 1998 and a second attack on his car in March 1999, when another man in the vehicle was killed and several people were injured.
Five people have already been tried for the attacks and the arrest warrant is unlikely to make any difference unless Mr Khodorkovsky returns to Russia, the BBC's Sarah Rainsford reports from Moscow.
Armed police raided the Moscow offices of Mr Khodorkovsky's Open Russia pro-democracy movement on Tuesday, in a move that authorities said was linked to allegations of tax evasion. The flats of at least seven activists who work for Mr Khodorkovsky were also searched.
Mr Khodorkovsky has always argued that the fraud charges for which he was imprisoned were politically motivated.
The exiled tycoon, who now spends much of his time in London. has repeatedly criticised President Putin in recent months. He said Tuesday's raids were acts of intimidation and the sign of an "authoritarian regime" nearing its "inevitable" end.
In further comments on Wednesday, Mr Khodorkovsky said the authorities were acting like bandits: "They've gone mad. I realised that yesterday."
After Mr Khodorkovsky was arrested in 2003, Yukos was broken up and taken over by a state oil firm. Last year an international arbitration court in The Hague said Russian officials had manipulated the legal system to bankrupt Yukos, and jail Mikhail Khodorkovsky.
The court told Russia to pay former shareholders in Yukos $50bn (£32bn) in compensation.
