A Turkish official says an employee has fired shots in a municipality building in southern Turkey, killing two of his colleagues, AP reported.

Soner Cetin, mayor for the town of Cukurova in Adana province, says the man entered the municipality building Friday brandishing a gun and opened fire on three of his colleagues. One of them was injured.

Cetin said the gunman was motivated by a “personal” feud between the employees.

State run Anadolu Agency says the man has been arrested.
