A bomb targeting security forces killed three people and wounded some 25 in southwest Pakistan on November 21.
The remote-controlled bomb was planted on a bicycle near a checkpoint run by police and the paramilitary Frontier Corps in the Satellite Town suburb of Quetta, the capital of Balochistan Province.
Senior police officer Samiullah Soomro said eight of the wounded are in critical condition.
In a separate incident, several people are feared dead and injured in a suspected suicide bombing near the Torkham border crossing between Pakistan and Afghanistan.
