MOSCOW - Russian President Vladimir Putin announced Friday that Russia will recognize the outcome of Ukraine's presidential vote this weekend but voiced hope that Ukraine would halt its military operation against activists in the east.

Speaking at an investment forum in St. Petersburg, Putin said Russia will "respect the choice of the Ukrainian people" and will work with its new leadership. He said Russia wants peace and order to be restored in Russia's neighbor.

Earlier, Putin had blamed the West for both encouraging a "coup'' in Ukraine when the nation's pro-Russian president was chased from power and for plunging the country into what he described as "chaos and a full-scale civil war.''

In a live televised address from Kiev, acting President Oleksandr Turchynov, who is not running, emphasized the importance of Sunday's vote to choose a new leader.

"Today, we are building a new European country the foundation of which was laid by millions of Ukrainians who proved that they are capable of defending their own choice and their country,'' Turchynov said. "We will never allow anyone to rob us of our freedom and independence, turn our Ukraine into a part of the post-Soviet empire.''

Authorities in Kiev had hoped that a new president would unify the divided nation, where the west looks toward Europe and the east has strong traditional ties to Russia. But they have now acknowledged it will be impossible to hold the vote in some areas in the east _ especially in Donetsk and Luhansk, where pro-Russians have declared independence.

Joao Soares, coordinator for an observation mission of the Organization for Security and Cooperation in Europe, said Friday he expects problems with voting in "less than 20 percent of the polling stations.''

Twenty-one candidates are competing Sunday to become Ukraine's next leader. Polls show billionaire candy-maker Petro Poroshenko with a commanding lead but falling short of the absolute majority needed to win in the first round; his nearest challenger is Yulia Tymoshenko, the divisive former prime minister, who is trailing by a significant margin.

If no one wins in the first round, a runoff will be held on June 15. Most polls predict Poroshenko's victory in that contest.

At a security conference in Moscow, Russian Foreign Minister Sergey Lavrov urged the West to reach a settlement based on mutual interests.

"If we sincerely want to help the Ukrainian people overcome this crisis, it's necessary to abandon the notorious zero-sum games, stop encouraging xenophobic and neo-Nazi sentiments and get rid of dangerous megalomania,'' Lavrov said.

Russia annexed Ukraine's southern Crimea Peninsula in March, triggering the worst crisis in relations with the West since the Cold War. Pro-Russians also have seized government buildings in eastern Ukraine and fought government troops for more than a month.

The head of the General Staff of the Russian military, Gen. Valery Gerasimov, on Friday criticized Ukrainian authorities for what he said was using artillery and other heavy weapons against civilians. He also charged that radical paramilitary forces and private security companies were spearheading the Ukrainian offensive.

The village of Semenovka on the outskirts of Slovyansk, a city that has been the epicenter of clashes for weeks, has seen continuous shelling by the Ukrainian government forces retaliating to rebel fire.

Early Friday, a house was destroyed by mortar fire that came from Ukrainian government side, but locals reported no casualties.

Shelling continued later in the day, targeting Slovyansk, where several other buildings were also damaged. There was no word of casualties.
