KARACHI: A low-intensity bomb attack in Karachi on Saturday wounded two people and caused panic, police said.

The remote-controlled roadside bomb exploded near the University of Karachi, close to the site where a Friday bomb attack killed three soldiers from the Pakistan Rangers paramilitary force.

Police said the target of the attack was not immediately clear, but the bomb exploded when a vehicle of Pakistan Rangers was passing near the university.

“It was a planted bomb. Two passers-by were injured,” Salam Sheikh, a senior police officer, told AFP.

A spokesman for the Pakistan Rangers said that troops remained unhurt in the incident.

No one has so far claimed responsibility for the attack, but nearly 4,700 people have been killed across Pakistan in attacks blamed on Taliban and other Al Qaeda-linked networks since 2007.
