String of terror attacks
Turkey has been roiled by a series of deadly attacks over the past year, claimed by ISIS or Kurdish militants.
And last month, ISIS claimed responsibility for shooting a Syrian religious leader and TV personality
in Gaziantep, which is near the border with Syria.
Other attacks so far this year include a bombing in January in Istanbul
that killed at least 10 people, a car bomb in Ankara that killed at least 28
in February, a March 13 bombing in Ankara
that killed 34, a March 19 suicide bombing in Istanbul
in which at least four were killed and a March 31 car bombing in Diyarbakir
that killed seven police officers.
Turkish police have also arrested four ISIS members suspected of preparing a terror attack on an International Workers Day demonstration in Ankara, Anadolu reported.
The suspects, who police said were from Syria, were detained at midnight Saturday after a surveillance operation, the news agency reported.
