At least eight al-Qaeda militants - some of whom were German nationals - have been killed in a drone attack in Pakistan, officials have told the BBC.

The suspected US drone fired two missiles at a house owned by a local tribesman in the Pakistani region of North Waziristan, the officials said.

At least three of the dead were said to be German, of Arab or Turkish origin.

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.
