STORY: U.S. President Obama said "I don't think we can count on anything" after U.S., Russia, Ukraine and EU together called for an immediate halt to violence in Ukraine.
Ukrainian, Russian and Western diplomats held emergency talks in Geneva seeking to resolve a confrontation that has seen pro-Russian fighters seize official buildings across eastern Ukraine while Moscow masses tens of thousands of troops on the frontier.
"All sides must refrain from any violence, intimidation or provocative actions," a joint statement issued after the Geneva talks said.
"All illegal armed groups must be disarmed; all illegally seized buildings must be returned to legitimate owners; all illegally occupied streets, squares and other public places in Ukrainian cities and towns must be vacated," it added.
Obama said it will not be clear for a few days whether those agreements are honored.
