ISTANBUL, Turkey: US Vice President Joe Biden is to visit Turkey on August 24, Prime Minister Binali Yildirim was quoted as saying by Turkish media on Saturday.

Yildirim, speaking to a group of Turkish journalists, said that Washington’s attitude on an extradition request for Fethullah Gulen, blamed by Ankara for orchestrating an attempted coup last month, had improved.

He said Ankara could not compromise with the United States over its extradition request.

Gulen denies any involvement in the attempted putsch in which 240 people were killed.

Yildirim said a total of 81,494 people including judges, soldiers and civil servants have either been suspended or sacked since the July 15 abortive putsch.
