Turkey blamed Kurdish militants for a blast that killed six people on a busy Istanbul shopping street on Sunday, and police detained a Syrian woman suspected of having planted the bomb among a sweep of 47 arrests.
The blast, the first to hit Istanbul in a number of years, has reminded Turks of a wave of attacks carried out by various militant groups targeting Turkish cities between mid-2015 and early 2017.
Following are some of those deadly attacks:
Jan 5, 2017 - A Turkish police officer and a courthouse employee were killed by a car bomb in the Aegean coastal city of Izmir while at least 10 people were wounded. Authorities said Kurdistan Workers Party (PKK) militants were behind the attack.
Dec 31, 2016 - Islamic State claimed responsibility for a New Year's Day mass shooting in which 39 people were killed after a lone gunman opened fire in a packed Istanbul nightclub.
Dec 17, 2016 - A car bomb killed 13 soldiers and wounded 56 when it tore through a bus carrying off-duty military personnel in the central city of Kayseri. An offshoot of the PKK claimed responsibility for the attack.
Dec 10, 2016 - Twin bombings, one planted in a car and the other strapped to a suicide bomber, killed 44 people, most of them police officers, and wounded more than 150 outside an Istanbul soccer stadium. A PKK offshoot, the Kurdistan Freedom Hawks (TAK), claimed responsibility for the attack.
