On July 15, a military coup attempt took place in Turkey. Ankara accused Islamic preacher Fethullah Gulen, who has been living in the US state of Pennsylvania since 1999, and his followers of playing a key role in the coup. Since July, Turkey has arrested hundreds of military personnel, activists and journalists on suspicion of links with Gulen.
