The bombing happened as people -- mostly police officers -- were lining up for the funeral procession at a mosque, CNN reported.
The blast killed 37 people, as well as the bomber, and injured 50 others, Quetta Police Chief Mir Zubair Mehmood said.
Most of the injured were taken to a local hospital for treatment, Mehmood said.
