At least 28 people have been killed and 61 others injured in a car bomb attack on military buses in the Turkish capital Ankara.
The government has said it does not know who was responsible for the explosion, which happened near the Parliament building as well as the country's military headquarters during the evening rush hour.
Some officials have blamed the Kurdish Workers Party (PKK), while others in the mostly Kurdish south-east say they believe militants from the so-called Islamic State group were behind the attack.
