According to Dogan News Agency, the delegation, led by AKP MP İbrahim Yildiz, was visiting local shopkeepers in Sanliurfa’s Cumhuriyet neighborhood in the Suruc district ahead of the June 24 elections.

A group of shopkeepers initially engaged in a heated argument with the AKP delegation, which turned violent in the end. Guns and clubs were used in the ensuing clash, reports said.

Four people, including a brother of MP Yildiz, were killed and eight, including four other brothers of Yildiz, were reportedly injured in the attack.

Several officials of the Democratic Regions Party (DBP), a local affiliate of the Kurdish issue-focused Peoples' Democratic Party (HDP), are among the casualties, local media reported.

According to MP Yildiz, the assailants told the delegation that they are supporting the Kurdistan Workers' Party (PKK) and asked why AKP members went there although they know it.

An investigation was launched as the police cordoned off the area.
