Lynne Tracy, the U.S. ambassador in Moscow, held talks Tuesday with Russian Deputy Foreign Minister Sergei Ryabkov and discussed the operations of Russian diplomatic institutions abroad, the RIA state news agency reported.

RIA cited Maria Zakharova, a spokeswoman for the Russian Foreign Ministry, as the source of the information.

Ryabkov, Russia's point man for relations with the United States, held a Monday news conference and, among other topics, discussed potential peace talks on Ukraine between Moscow and Washington.

Kremlin spokesman Dmitry Peskov said earlier Tuesday he had no information about unconfirmed reports on Telegram that U.S. Middle East envoy Steve Witkoff might have flown into Moscow and that no meetings with him were on the agenda.
