Wanted by both the US and Yemen, Anwar al-Awlaki was accused of being an al-Qaeda preacher and mentor. He was killed on Friday by a US drone strike in the province of al-Jawf, north of the Yemeni capital Sanaa.

Barack Obama, the Us president, said the killing of Awlaki was a "significant milestone in the broader effort to defeat al-Qaeda and its affiliates".

While holding Awlaki "directly responsible" for the deaths of many Yemeni citizens, Obama cautioned that al-Qaeda in the Arabian Peninsula was still dangerous although it remained a "weakened" outfit.

Will the death of the US-born cleric have much of an impact on the organisation? What does al-Awlaki's death mean for thousands of angry Yemenis calling for a regime change? And will it help President Saleh as he clings to power?
