At least two people were killed and several others injured in a bomb explosion in southern port city of Karachi on late Friday, police said.
Initial investigations suggested that the bomb was planted underneath a handcart in a makeshift market in the eastern outskirt of Karachi, Irfan Bahadur, the city police chief, told media.
Bahadur said the bomb was detonated through a remote control.
Footage aired on local broadcaster Geo News showed rescue workers shifting the dead and injured into the ambulances as blood-soaked pieces of clothes, shoes, glasses, and other belongings were scattered on the road and the sidewalks.
No group has yet claimed responsibility for the attack.
Karachi, the country's most populous city and the commercial capital, has long been notorious for sectarian and political violence and gang wars that have killed thousands over the last three decades.
However, the security forces have managed to reduce the level of violence following a military-backed operation launched in 2013 in the metropolis.
