Turkish security forces arrested 58 people in operations across 32 provinces for alleged links to the outlawed Islamic movement of Fethullah Gülen, accused of plotting a 2016 military coup attempt. Prosecutors in the southeastern Gaziantep province have issued arrest warrants for 121 suspects, including serving military personnel, state-run Anadolu news agency reported on Tuesday. Turkey says that followers of Islamic cleric Gülen, who lives in self-imposed exile in the United States, masterminded the failed coup of July 2016. Tens of thousands of civil servants and members of the military have been expelled or arrested over links to the group since the attempted putsch. Gülen denies involvement. The United States has yet to approve a request by the Turkish government to extradite him to face trial citing lack of evidence.
