Turkey's prime minister says a group within Turkey's military has engaged in what appeared to be an attempted coup.

Binali Yildirim told NTV television: "it is correct that there was an attempt."

Yildirim didn't provide details, but said Turkey would never allow any "initiative that would interrupt democracy."

Earlier, military jets were heard flying over the capital, Ankara.

Media reports said ambulances were seen in front of the Turkey's military headquarters.
