An explosion hit Turkey's capital Ankara on Sunday killing at least 27 people and injuring 75 others, sources said.
Many ambulances were sent to the scene after a bomb-laden car exploded at square Kizilay at about 18:35 local time and set a number of vehicles on fire, private broadcaster NTV reported, according to Xinhua.
Witnesses said smoke could be seen rising above the area from a distance, and square Kizilay has been closed fearing a possible second explosion.
This is the third major blast in the Turkish capital since last October.
On October 10, 2015, alleged Islamic State (IS) militants bombed a peace rally near Ankara railway station near a major city thoroughfare, killing at least 103 people.
On February 17, a suicide car bomb targeted military shuttles in the capital city, killing at least 29 people and injuring 81 others.
