A chaotic night began late Friday with reports of soldiers trying to wrestle control of bridges and key functions in major cities, and turned into a nightmare when army helicopters began airstrikes and shelled key locations in the capital, Ankara, Anadolu reported.
Bombs struck near the Turkish Grand Assembly, witnesses said.
Airborne shelling at several locations including the ruling AK Party headquarters, the presidential complex and the General Staff have been reported.
Prime Minister Binali Yildirim later announced a no-fly zone has been enforced above Ankara, adding that army commanders, including Chief of Staff Hulusi Akar, are on duty and working to stop the illegal military action.
