A year of deadly attacks

It was a bloody start to 2017 in Turkey, which has suffered a year of attacks by Islamic State jihadists and Kurdish militants and a failed coup against President Recep Tayyip Erdogan.

Following are the worst attacks in Turkey over the past year:

Nightclub terror

Ambassador assassinated

December 19: Russia's ambassador to Turkey, Andrei Karlov, is shot dead at an Ankara art gallery by an off-duty policeman who claims he is acting to avenge the conflict in Syria, especially Aleppo. The government accuses the group of US-based cleric Fethullah Gulen, blamed for the July 15 failed coup.

December 17: 14 soldiers are killed and dozens of other people wounded in a suicide attack targeting a military bus in the central city of Kayseri. The Kurdistan Freedom Falcons (TAK), seen as a radical offshoot of the outlawed Kurdistan Workers' Party (PKK), claims responsibility.
