KIEV - Russian Foreign Minister Sergei Lavrov accused the United States of being behind the political upheaval in Ukraine and said Moscow would respond if its interests came under attack.
Lavrov's comments came a day after US Vice President Joe Biden was in the Ukrainian capital with promises of support for the pro-Western government, and a warning to Russia not to interfere in Ukraine.
The crisis in Ukraine, now in its fourth month, has dragged Russia's relations with the West to their lowest since the Cold War. In the east, pro-Russian armed separatists have seized about a dozen public buildings and are defying Kiev's authority.
A further escalation could lead to damaging economic sanctions, and raises the risk of a disruption to the Russian gas supplies on which Europe depends.
NATO says Russia has built up a force of about 40,000 troop in its border with Ukraine. Moscow says some are stationed there permanently, while others have been deployed as a precaution to protect Russia from the instability in Ukraine.
In Moscow, Lavrov said Moscow would respond if its interests, or the interests of Russian citizens, were attacked.
"Russian citizens being attacked is an attack against the Russian Federation," he said according to excerpts of an interview with the Russia Today news channel.
Washington said that suggestion was "ludicrous", while NATO's deputy secretary general, Alexander Vershbow, said Russia must de-escalate the situation and avoid inflammatory rhetoric and misrepresentations of the situation inside Ukraine.
Russia justified its intervention in Crimea earlier this year by saying it had to defend Russians living there. In eastern Ukraine some people hold Russian passports.
Ukraine called on Moscow to pull troops back from the border, saying it feared pro-Russian separatists could use their proximity to provoke a Russian invasion.
Lavrov's ministry, in a separate statement, accused the United States and the interim government in Kiev of a "distorted interpretation" of an international accord, signed in Geneva last week, under which illegal armed groups in Ukraine are to disarm and give up buildings they have occupied.
Russia said that applies not only to the pro-Russian separatists in the east, but also to groups in Kiev whose protests helped bring Ukraine's new government to power.
Earlier, Ukraine's government relaunched a security operation to crack down on the pro-Russian armed groups after an Easter pause and said it had the backing of the United States.
Kiev's decision to resume its security operation in the east was prompted in part by the discovery of two bodies in a river in eastern Ukraine. One body was that of Volodymyr Rybak, a member of the same party as Ukraine's acting president.
The United States and NATO have made clear they will not intervene militarily in Ukraine. But the Pentagon said it was sending about 600 soldiers to Poland and the three Baltic states for infantry exercises, to reassure NATO allies.
Russian gas giant Gazprom has said it will turn off supplies to Ukraine next month unless Kiev pays its outstanding debts. That would have a knock-on effect on deliveries to Europe, because much of the gas shipped westwards has to pass through Ukrainian territory.
The crisis in Ukraine began when Yanukovich, under pressure from Moscow, pulled out of a planned cooperation agreement with the EU. Pro-Western protesters took to the streets and Yanukovich fled after bloody clashes.
As a caretaker leadership of pro-Western protest leaders took over the government in Kiev, the Kremlin sent its forces into Ukraine's Crimea Peninsula, and shortly after annexed the region. Moscow said it acted to protect local people who were being persecuted by Kiev's new rulers, while the West called it an illegal land grab.
In areas under the separatists' control, there was growing evidence of arbitrary rule by self-appointed local officials, backed up by heavily armed militias, and of violence being meted out against opponents.
A video released on a local news site, gorlovka.ua, purported to show Rybak, the councillor whose body was found in a river, being confronted by an angry crowd outside the town hall in Horlivka, where he was a councillor.
Rybak can be seen being manhandled by several men, among them a masked man in camouflage, while other people hurl abuse.
After several minutes, Rybak appears able to walk away. The Interior Ministry said he was seen being bundled into a car by masked men in camouflage later that day. His body, and that of a second man, was found on Saturday in a river near Slaviansk.
In nearby Slaviansk, pro-Russian militia were holding three journalists, including a U citizen, Simon Ostrovsky, from the online news site Vice News.
The United States said the detentions amounted to kidnappings which violated the Geneva agreement.
