Pakistani Police discovered at least three hand grenades lying near a private hospital in Karachi, (Geo News) reported. Police said the grenades, found just yards away from a private healthcare facility near NIPA Chowrangi, were live. Bomb diffusers were called in to make the bombs harmless. It is pertinent to mention that a couple of days back extortionists attacked a supermarket, in the same neighbourhood, with a grenade, which damaged two vehicles and injured one person.
