A young man and woman were killed in Shangla on Monday in a suspected 'honour killing', police said.
Zarghuna Bibi, 23, and Ziaul Haq, 27, were shot allegedly by the woman's brothers after they found the two in a 'compromising position', Deputy Superintendent of Police (DSP) of Puran Circle Zeerab Gul said.
