ANKARA, Turkey — Three gunmen opened fire on security forces at a highway roadblock in central Turkey Thursday, killing a soldier, a police officer, and a truck driver whose vehicle they escaped in, a regional governor said.
Two of the men were later caught at a clinic seeking medical help for their wounds, according to the governor of Nigde, where the attack took place.
As the suspects were being taken to a hospital under guard, hundreds of people gathered there to protest the attack, coming under pepper spray fire from police, according to the Dogan news agency.
Necmeddin Kilic, the Nigde governor, said the men opened fire on soldiers manning the roadblock and on police who were called in for help. They escaped in a truck after killing its driver. He said the men were foreigners.
Prime Minister Recep Tayyip Erdogan described it as a ‘‘terror act.’’ No group was identified.
Kurdish, leftist, and radical Islamist groups have carried out attacks in Turkey in the past. Kurdish rebels are observing a cease fire declared last year as part of efforts to end a conflict that has killed thousands since 1984.
