27 killed in Ankara explosion

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.
