Twenty-seven people were killed and 75 were inured during an attack in the Turkish capital of Ankara, the province's governor told NBC News.
The blast, which local media attributed to a car bomb, occurred on the city's main boulevard, Ataturk Bulvari, close to Ankara's main square, Kizilay.
The private NTV news channel said a car, believed to be laden with explosives, detonated close to a bus.
Several vehicles then caught fire, the station said. The area is close to government offices, including ministries.
The deadly explosion — the third in the city in five months — came just three weeks after a suicide car bombing in the capital targeted buses carrying military personnel, killing 29 people.
A Kurdish militant group which is an offshoot of the outlawed Kurdish rebel group, the Kurdistan Workers' Party, or PKK, claimed responsibility for the Feb. 17 attack.
