ST. PETERSBURG, Russia - President Vladimir Putin pledged Friday that Russia will respect the results of Ukraine's presidential election, a strong indication the Kremlin wants to cool down the crisis. But new violence and rebel vows to block the balloting made prospects for peace appear distant.
New clashes were reported between pro-Russia separatists and government forces in eastern Ukraine as Kiev continued an offensive to try to halt the uprising.
Associated Press reporters saw two dead Ukrainian soldiers near the village of Karlivka, and another body near a rebel checkpoint, both in the Donetsk region. A rebel leader said 16 more people died Friday in fighting there - 10 soldiers, four rebels and two civilians - but there was no immediate way to verify his statement.
In Kiev, the Defense Ministry said 20 insurgents were killed in an attack on a convoy of government troops Thursday by about 500 rebels, the largest insurgent assault yet reported. The clash could not be independently confirmed and it was unclear why such a large attack in a populated region would have gone unreported for more than a day. The ministry also said one soldier was killed Friday near the same area.
On Thursday, 16 troops were killed near the separatist stronghold of Donetsk in the deadliest raid yet on Ukrainian troops.
Ukraine's caretaker president urged all voters to take part in Sunday's crucial ballot to "cement the foundation of our nation." Yet it was uncertain whether any voting could take place in the east, where rebels who declared the Donetsk and Luhansk regions independent have vowed to block what they call an election for the leader of a foreign country.
Authorities in Kiev had hoped that a new president would unify the divided nation, whose western regions look 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. Election workers and activists say gunmen there have threatened them and seized their voting rolls and stamps.
Kiev and Western countries allege Russia is fomenting the unrest, possibly with the aim of justifying an invasion. Russia denies it, but it is showing signs of wanting the crisis to settle down. Moscow has been hit by U.S. and European sanctions after it annexed Crimea from Ukraine in March.
