High-level US-Russia talks now 'up in the air' - American official
Earlier, the White House said President Barack Obama may forego an anticipated Moscow summit this fall following Russia's decision to grant asylum to fugitive former US spy agency contractor Edward Snowden.
"We see this as an unfortunate development and we are extremely disappointed by it," White House spokesman Jay Carney said.
Asked whether Moscow's granting of a year's asylum in Russia to Snowden would affect a decision to meet with Russian President Vladimir Putin for a summit in September, Carney said, "We are evaluating the utility of the summit."
