Hull City have signed Burnley winger Anass Zaroury on loan until the end of the season and Trabzonspor midfielder Abdulkadir Omur for an undisclosed fee.
Morocco international Zaroury, 23, has made just six Premier League appearances since last season's promotion to the top flight.
Omur, 24, has signed a three-and-a-half-year deal with the Tigers.
He scored 25 goals in 211 games for Trabzonspor, winning both the Super Lig and Turkish Cup with the club.
Meanwhile, Hull's Peru midfielder Yuriel Celi, 21, has had his loan spell with Lima-based Club Universitario de Deportes extended for another year.
