Two policemen killed in car bomb blast in Turkey
A car bomb struck the entrance of a Turkish police station on Sunday, killing two policeman and wounding 22 other people, officials said.
Four civilians were among those injured in the blast at Gaziantep, according to the governor of the province Ali Yerlikaya.
The blast shattered the windows of nearby buildings.
The police station is close to offices for the governor and mayor. Gaziantep is also home to the offices of international aid organisations focused on the conflict in neighbouring Syria.
There was no immediate claim of responsibility for the attack. Turkey has suffered multiple bombings in recent months linked either to Kurdish militants or the Islamic State group.
May 1 International Labor Day demonstrations in Gaziantep were cancelled for security reasons, the private Dogan news agency reported.
Speaking in Ankara, the Turkish capital, Prime Minister Ahmet Davutoglu expressed his condolences and wished a speedy recovery to those wounded in "the heinous terrorist attack".
Police in Ankara, meanwhile, carried out anti-terror operations overnight and detained four suspected IS members allegedly planning to attack May Day demonstrators, the Anadolu Agency reported.
In Istanbul, police imposed tight security measures and used water cannons and tear gas on May Day demonstrators who sought to rally in non-designated areas.
In a separate incident on Sunday, four people were wounded after two rockets hit a car park and a house garden in Kilis, another town near the Syrian border, the Anadolu Agency reported. It said the Turkish military retaliated by firing at IS targets across the border in Syria, killing nine militants. I
