ANKARA, Turkey — Members of Turkey's armed forces said they had taken control of the country, but Turkish officials said the coup attempt had been repelled early Saturday morning in a night of violence that left at least 17 dead, according to state-run media. Explosions, gunfire and a reported air battle between loyalist forces and coup supporters erupted in the capital throughout the night and Turks heeded the president's call to take to the streets to show support for his embattled government. The state-run Anadolu Agency reported a bomb hit the Turkish parliament in Ankara.
