In an interview with Ekho Moskvi radio station, President Boris Yeltsin's spokesman Dmitry Yakushkin said, there were all indications that military strikes against Yugoslavia will only be expanded in the next few days.``Yeltsin was ready to take all measures to stop this action, not excluding the military ones," he said emphatically, not giving any details about what concrete military measures the Kremlin was planning to take.

Yeltsin has already sent a letter to the Yugoslavian President Slobodan Milosevic, condemning NATO air strikes, Yakushkin said, adding italso contained "concrete measures" designed to deal with the NATO aggression against Yugoslavia.

The Kremlin has hinted a summit between Yeltsin and Milosevic was possible in Moscow to sort out the questions around the Kosovo crisis.The NATO air strikes against Yugoslavia have provoked an unprecedented anger across Russia, with most Russians opposing the NATO action, whether they are communists, nationalists or liberal reformers.

The State Duma, parliament's lower house, at an emergency session Friday, passed overwhelmingly a resolution condemning the NATO air strikes.The Duma also recommended Yeltsin to recall a draft law on ratifying the START II treaty, as a response to the NATO action.

Appearing at the state-run television station ORT, speaker of the Duma, Gennady Seleznev said, Russia must start supply arms to Yugoslavia, lifting the UN-imposed arms embargo against Belgrade.

Speaking at the Duma session, Russian Foreign Minister Igor Ivanov said, if NATO doesn't stop the aggression, Russia willdemand an emergency session of the UN General Assembly give all members of the world community the opportunity to vote.

A spokesman for Russian Defence Ministry, has said, Russia was calling off its Y2K-related cooperation with the Pentagon under a recent agreement to set up a US-Russian centre to monitor the computer networks of Russian strategic missile forces.

US Embassy in Moscow

MOSCOW: Machine gun bullets were today fired at the US embassy, scene of repeated protests against the NATO bombing of Yugoslavia, but there were no reports of injuries. The shots were fired from a white jeep, hitting the side of the building. Associated Press photographers, who heard the shooting, estimated at least ten shots were fired as frightened bystanders hurled themselves on the ground. An embassy spokesman, who declined to be named, said nobody in the embassy had been injured, but declined to comment further.

An eyewitness said the jeep stopped and a man in a ski mask and camouflage fatigues got out and triedto fire two grenade launchers. When neither launcher worked, the man opened fire with a semi-automatic rifle, he said. The two grenade launchers were left in front of the embassy. Police officers covered them with bullet proof jackets.

Police officers on foot chased after the vehicle after the shooting, but it escaped. One officer told AP he had opened fire at the fleeing vehicle with his pistol.Scores of police officers and members of the FSB, the Russian intelligence service, ringed the front of the embassy after the attack.

People protesting the NATO air-strikes on Yugoslavia have been demonstrating outside the embassy for the past four days. There were scores of arrests on Thursday. The attack came as three of Russia's top liberal officials set off on a peace mission to appeal to world leaders, including Yugoslav officials, US vice-President Al Gore and Pope John Paul II, to resume talks on ending the Kosovo crisis.

BELGRADE: NATO probably faced the music -- not just when it lost a stealthfighter shot down by the Yugoslav Air Defence but also when Belgraders held a rock concert in defiance of ``the law of power''. Hundreds of thousands of Belgraders thronged the Liberty Square in the downtown here this afternoon to attend the rock concert. ``We are ready to stand up and fight until final victory,'' said a broadcast message on Belgrade TV channel, Studio B. ``Belgrade is defying aggression by organising concert.

Against the law of power, citizens of Belgrade have responded with the power of love and dedication to justice and truth and by doing so Belgrade has mocked the savage power,'' said Studio B.
