Drone strike kills senior al-Qaeda leader

Senior al-Qaeda leader Abu Yahya al-Libi was killed in a drone strike in Pakistan on Monday, a US official has told the BBC.

US officials said Libi was the target of an attack which hit a volatile tribal area of Pakistan's north-west, killing 15 suspected militants.

The BBC's Adam Brookes said the US was portraying this as another very serious blow against al-Qaeda leadership.
