One policeman was killed in Karachi on Saturday when unknown gunmen opened fire near the City Courts. The gunmen opened fire at a group of policemen who were escorting a number of prisoners to the courts and threw a hang grenade amid the crowd. One policeman was killed as a result of the attack and four prisoners were able to flee along with the gunmen. Security officials followed one of the gunmen, who fled to nearby Jodia Bazaar and killed himself. One hand grenade was recovered from his possession, while search teams have been sent to other areas to locate the remaining gunmen.
