MOSCOW, March 28. /TASS/. The US Embassy in Moscow has not received any documents over the past three months justifying the detention of US citizen Paul Whelan suspected of spying, the embassy said on Twitter.

"Today is three months since the arrest of US citizen Paul Whelan who has been held in custody without any evidence being furnished. Investigators assured that the signed documents had been sent to us by post, but no one sent them," the diplomatic mission noted. "What are we to make of this? Where is the evidence?"
