One person was killed and four others injured in an explosion at a police compound in the southeastern Turkish city of Diyarbakir on Tuesday.

The explosion took place at around 11:00 a.m. local time (0800 GMT) in front of a building of local security forces during the repair of an armoured vehicle. The sound of the explosion was heard and a large plume of smoke could be seen rising from the area, local media reported, citing witnesses.

The country's Interior Minister Suleyman Soylu denied that the incident was a terror attack. "The blast was in a part of the building for riot police, where maintenance is carried out on vehicles," CNN reported the minister as saying.
