Karachi - Nine people have been wounded after motorcycle-borne attackers hurled grenades at a tea stall in Karachi, Pakistan's largest city and commercial hub, police said.
Neither the assailants nor their motive for Monday's attack had been identified, a police officer said, adding it was too early to blame a particular militant group of individuals for the attack.
“At least nine people were injured when two men on a motorcycle threw two hand grenades on a roadside tea stall,” in the city's Miran Naka neighbourhood, police official Pervez Bhatti told reporters.
On Saturday, a home-made bomb left by two motorcyclists in a bin failed to explode outside the international Red Cross office in Karachi, police said, although the detonator caused a small blast.
Karachi is plagued by killings linked to political and ethnic tensions as well as criminal gangs, but Islamist militant violence is also on the rise in the city of 16-million people whose port is a hub for Nato supplies bound for Afghanistan.
Last month, it took the navy 17 hours to fight off a handful of militants who killed 10 security officials and destroyed two US-made aircraft at the only naval air base in Karachi. - AFP
