MOSCOW -- Russia's security chief yesterday accused U.S. and other foreign intelligence services of using non-governmental organizations that promote democracy to spy on Russia and bring about political upheaval in former Soviet republics.

The remarks by an ally of President Vladimir Putin reflect concern in the Kremlin over its waning regional clout following the ascent of pro-Western governments on its borders.

"Along with classic forms of influence on political and economic processes, foreign intelligence agencies are ever more actively using nontraditional methods," including working through "various non-governmental organizations," Federal Security Service chief Nikolai Patrushev told lawmakers.

"Under cover of implementing humanitarian and educational programs in Russian regions, they lobby the interests of the states in question and gather classified information on a broad spectrum of issues," he said.

Patrushev reiterated claims by Russian officials who have accused the United States and other Western nations of using government-funded groups to aid opposition forces that have brought down governments in former Soviet republics in the past two years.

Non-governmental organizations, or NGOs, that Patrushev accused of involvement in espionage -- including the Peace Corps -- denied the allegations. And White House press secretary Scott McClellan said he was not aware of the accusations by Russia's security chief. "I have not seen those comments," he said, "and I have no idea what he is referring to."

Just this week, President Bush visited Georgia, site of the 2003 Rose Revolution -- first of the uprisings against entrenched leaders in ex-Soviet republics that later spread to Ukraine and Kyrgyzstan. On Monday, Bush stood beside Putin in Red Square for a ceremony marking the 60th anniversary of the defeat of Nazi Germany.

"Our opponents are steadily and persistently trying to weaken Russian influence in the Commonwealth of Independent States and the international arena as a whole," Patrushev said. "The latest events in Georgia, Ukraine and Kyrgyzstan unambiguously confirm this."

With Bush joining domestic critics who question Putin's tightened control over electoral processes in Russia and pointedly advocating democracy in visits to Russia's neighbors, the Kremlin is sensitive about foreign influence as elections approach in 2007 and 2008.

Russian politicians have claimed that U.S. government money, funneled through NGOs that promote democracy, was a major force behind the protests that swept Western-leaning opposition leaders to power in Georgia and Ukraine, and was also a factor in Kyrgyzstan.

U.S. officials say the programs of U.S. groups -- whose activities include providing election training, underwriting exit polls and supporting independent media -- are not interference, but acknowledge that some of the money has helped opposition groups.

Patrushev suggested that Russia believes that the next Western target is Moscow ally Belarus, where U.S. officials have not masked their disgust at authoritarian President Alexander Lukashenko. Bush has called Belarus the last dictatorship in Europe, and Secretary of State Condoleezza Rice said it was time for a change in the country, where a presidential election is to be held next year.

Patrushev said the International Republican Institute, a group that promotes democracy and gets most of its money from the U.S. government, held a meeting in Slovakia last month during which "the possibility of continuing 'velvet revolutions' on the post-Soviet space was discussed." He also claimed that $5 million was earmarked for IRI funding of opposition groups in Belarus this year.

IRI spokeswoman Lisa Gates said in Washington that the organization spends about $500,000 annually on programs in Belarus, and none of it goes to political parties.
