At least thirty people were killed and 126 were wounded in two explosions outside the main train station in the Turkish capital Ankara on Saturday, the Turkish Interior Ministry said.
A Reuters reporter at the scene saw at least 15 bodies covered by flags, with bloodstains and body parts scattered on the road.
The Turkish government officials say the blast was a terrorist attack and investigation into the attack is underway.
Last month, five children were wounded when a bomb tore through a street in the Turkish city of Diyarbakir, where deadly clashes followed the collapse of a ceasefire by Kurdish militants.
A separate blast in the town of Tatvan wounded five soldiers when their vehicle passed over an explosive left in a ditch by the road, security sources said.
Turkey has been widely criticized by the international media for aiding and abetting terror outfits in neighbouring Syria,
