Putin: Russia has right to use force in Ukraine

Ukraine has accused Russia of violating a bilateral agreement on conditions of a Russian lease of a naval base in Crimea that restricts troop movements, but Russia has argued that it was acting within the limits set by the deal.

Russia's ambassador to the United Nations, Vitaly Churkin, said Monday at the U.N. Security Council that Russia was entitled to deploy up to 25,000 troops in Crimea under the agreement.

Churkin didn't specify how many Russian troops are now stationed in Crimea, but said that “they are acting in a way they consider necessary to protect their facilities and prevent extremist actions.”

Churkin said that Russia wasn't trying to ensure the return to power of Yanukovych, but still considers him the legitimate leader of Ukraine and demands the implementation of a Western-sponsored peace deal he signed with the opposition that set presidential elections for December. Russian envoy at those talks did not sign the deal.

Yanukovych fled the capital hours after the deal was signed and ended up in Russia, and the Ukrainian parliament set the presidential vote for May 25.

There was no sign of tensions elsewhere in Crimea early on Tuesday. A supposed Russian ultimatum for two Ukrainian warships to surrender or be seized passed without action from either side, as the two ships remained anchored in the Crimean port of Sevastopol. Russian Defense Ministry spokesman Vladimir Anikin said late Monday that no ultimatum had been issued.

Early on Tuesday, the Kremlin said Putin ordered troops participating in military exercises alongside Russia's western border to return to their permanent bases.
