LONDON - The wife of a Belarusian dissident who disappeared after flying to Turkey three months ago says she is pinning her hopes of finding him on U.S. President Donald Trump's new special envoy to Belarus.

Anatol Kotau, 45, flew into Istanbul from Warsaw early on the afternoon of Thursday, August 21. In the following hours, he exchanged a series of Telegram messages with his wife Anastasia in Poland and promised to let her know where he would be staying.
