AN American drone strike was launched in Kurram Agency but it missed its target, reported a private TV channel on Tuesday. The drone fired a missile on a vehicle in Shabak area of Lower Kurram, four kilometres from the Pak-Afghan border but the missile missed the target. This was the fourth attack by the US drones during the last 36 hours. US drones fired three missiles in Lower Kurram the other day, killing 11 people. Obama-led administration has beefed up its drone attacks on Pakistani soil in a bid to target Al-Qaeda and Taliban-linked terrorists especially in North and South Waziristan areas.
