Wagner Group head Yevgeny Prigozhin has landed in Belarus, where he is staying in one of the few hotels in the capital Minsk that has no windows, a US official said. 

Prigozhin went to Belarus as part of a deal to end his group's armed rebellion and was last seen in public leaving the southern Russian city of Rostov-on-Don after withdrawing his troops. 

There has been speculation about his whereabouts since then, but US Senate Intelligence Chairman Mark Warner told NBC News that Prigozhin is in Minsk. 

"He is in one of the only hotels in Minsk that does not have any windows," he said, adding that he is hiding from the attempted murder.
