A British spy had a key part in killing al-Qaeda leader and 9/11 attacks mastermind Ayman al-Zawahiri, we can reveal.
An Afghanistan-based MI6 agent supplied information to help locate Zawahiri, who was assassinated in a CIA drone strike on Sunday.
The drone launched two Hellfire missiles which killed the 71-year-old as he stood on the balcony of a safehouse in Aghanistan’s capital, Kabul.
