A huge explosion has taken place in the Kizilay neighbourhood of the Turkish capital Ankara, with reports of injuries.
Turkish broadcaster NTV said the blast was caused by a car bomb, but this has not been confirmed.
Witnesses say the explosion happened near the main bus station on Ataturk boulevard and close to many government ministries. Some vehicles were on fire.
Last month, a bomb attack on a military convoy in Ankara killed 28 people.
A Turkey-based Kurdish militant group said it carried out that attack.
The Turkish Hurriyet newspaper said the latest blast was in the Guvenpark in Kizilay.
