MOSCOW, May 21 (Reuters) - The Kremlin said on Wednesday that Russia and the United States were working on a prisoner swap between the two countries, but that the timing of the exchange was not yet known.
U.S. President Donald Trump and Russian President Vladimir Putin discussed a possible prisoner exchange involving nine people from each side during a phone call on Monday.
Asked for an update, Kremlin spokesman Dmitry Peskov said that what he called "the appropriate government agencies" from both sides were in touch with each other on the issue.
A source close to the Kremlin has told Reuters that the U.S. side had previously provided Moscow with a list of nine Americans jailed in Russia that Washington wants returned.
