Yanukovich's flight into hiding left Putin's Ukraine policy in tatters, on a day he had hoped eyes would be on the grand finale to the Sochi Olympics. The Kremlin leader spoke on Sunday with German Chancellor Angela Merkel, whose foreign minister had brokered a short-lived truce in Kiev on Friday.

They agreed Ukraine's "territorial integrity" must be maintained, Merkel's spokesman said in a statement.

British Foreign Secretary William Hague was asked if Russia might "send in the tanks" to defend its interests among ethnic Russians in the east and on the Crimea peninsula, where Moscow bases its Black Sea Fleet: "It would really not be in the interests of Russia to do any such thing," he told the BBC.

Earlier this month, a Kremlin aide had warned that Moscow could intervene.

It is unlikely the United States and its allies in NATO would risk an outright military confrontation with Russia but such echoes of the Cold War underline the high stakes in Ukraine, whose 46 million people and sprawling territory are caught in a geopolitical tug of war.

EUROPEAN OFFERS

EU officials offered financial aid to a new government and to revive a trade deal that Yanukovich spurned under Russian pressure in November, sparking the protests that drove him from office after 82 deaths last week, many from police sniper fire.

In addition to any economic assistance the EU might offer, the U.S. has also promised help. Budgets are tight on both sides of the Atlantic, and international creditors may be wary of Yanukovich's opponents, whose previous spell in government was no economic success, but a desire to avoid instability and back what looks to Western voters like a democratic movement menaced by Russian diktat may loosen purse strings, at least to tide Ukraine over until elections.

In Russia, where Putin had wanted Ukraine as a key part in a union of ex-Soviet states, the finance minister said the next tranche of a $15-billion loan package agreed in December would not be paid, at least before a new government is formed.

Russian Foreign Minister Sergei Lavrov, according to his office, told U.S. Secretary of State John Kerry the opposition had "seized power" by force by ignoring an EU-brokered truce that would have left Yanukovich in office for the time being.

But even lawmakers from Yanukovich's own party voted for his removal on Saturday and blamed him and his entourage for the crisis. Business "oligarchs" also distanced themselves from a man long seen as their representative in the presidency.

In a mark of passions dividing Ukrainians along a historic faultline between Russian and Ukrainian cultures, local television in Kerch, in eastern Crimea, showed a crowd hauling down the blue-and-yellow Ukrainian flag in front of the town hall and hoisting the white, blue and red Russian tricolour.
