Khodorkovsky vows to help prisoners
Former Russian oil tycoon Mikhail Khodorkovsky has vowed to do all he can to secure the release of political prisoners in Russia after his pardon and release.
Khodorkovsky spoke at a packed and tumultuous news conference in Berlin two days after he was released and immediately flew to Germany.
The 50-year-old said he should not be viewed as a symbol that there are no political prisoners in Russia and said he would do "all I can do" to secure the release of others.
He thanked media pressure for helping secure his release.
