Intelligence officials in Pakistan say at least eight al-Qaeda militants have been killed in a strike by a United States drone, several of whom were German nationals.
Two missiles fired by the drone apparently hit a house in North Waziristan in the north west of the country.
Officials say at least three of the dead were said to be German, of Arab or Turkish origin, the BBC reports.
There have been 26 such strikes in the area in the past month, killing several high-profile militants.
Analysts have linked the increasing frequency of US drone attacks with current reports of an alleged al-Qaeda plot to attack European cities.
Several countries have issued travel warnings to their citizens, and US intelligence sources have linked the plot to militants in Pakistan.
