NOVO-OGARYOVO, near Moscow, August 1 (Itar-Tass) -- Russia did not get any signals from the U.S. on a possible cancelation of Barack Obama's visit to Moscow, President Putin's aide Yuri Ushakov said Thursday.

"We are aware of the kind of climate that is forming around this /the situation with the former CIA technology analyst Edward Swoden/ that is forming in the U.S. but we haven't received any signals from the U.S. Administration," he said.
