Islamabad: A US drone missile strike on Sunday killed eight people and injured several others in Pakistan's tribal area of North Waziristan along the Afghan border, security officials said.

Four missiles destroyed a house and blew up two vehicles, at Shewa located 40 kilometres northeast Miramshah, the main town in North Wazirsitan, which has witnessed a significant surge in drone strikes lately.

The increased frequency of drone attacks followed a reported discovery by US and European intelligence agencies of an Al Qaida plot being hatched in North Waziristan to carry out terror attacks in European cities.

Last week a drone missile attack in Mir Ali area of North Waziristan reportedly killed four German and three Arab militants.

Around 25 drone attacks in Pakistani tribal areas, most in North Waziristan, were reported in September, the highest number in a single month in the last six years. In the current month of October five attacks have taken place so far.

The US has dramatically increased the number of CIA drone strikes in Pakistan's tribal belt. The US rarely acknowledges the covert missile strike programme, but officials have said privately that they have killed several senior Taliban and Al Qaida commanders.
