MOSCOW: Russia's foreign intelligence chief on Wednesday accused the United States of protecting Belarus opposition leader Svetlana Tikhanovskaya and allocating $20 million to promote anti-government protests that erupted after disputed presidential elections.

Sergei Naryshkin, who heads the Russian Foreign Intelligence Service (SVR), said Washington had taken the former presidential candidate Tikhanovskaya and other activists "firmly under its wing" in a statement published by Russian news agencies.

Tikhanovskaya, a 38-year-old former English teacher and translator and more recently a full-time mother, stood for president after the jailing of her husband, popular video blogger Sergei Tikhanovsky.

Her campaign proved a surprise success and she claimed victory over longtime leader Alexander Lukashenko in disputed polls.

Tikhanovskaya took shelter in neighbouring Lithuania after coming under official pressure and many of her leading supporters have since been forced out of Belarus or jailed.

One of her allies, Maria Kolesnikova, was formally charged on Monday with undermining national security, investigators said, adding she would remain in police custody. Naryshkin said the West had started to prepare protests long before the August 9 election, adding that the US had given various rights groups $20 million (17 million euros) in funding from last year.

The money went to "independent bloggers", he said, while "experienced American instructors" gave training to the most promising activists in countries including Poland and Ukraine.

"The protests from the start were well-organised in nature and coordinated from abroad," Naryshkin said.

"According to the SVR's information, the US is playing a crucial role in the current events in Belarus."
