Al-Qaida warns Americans that revenge will come

Al-Qaida has warned that the US has committed a “big mistake” and a “serious sin” in killing Osama bin Laden and is calling on Muslims to avenge his death.

In a statement posted on the internet, al-Qaida’s official online media organisation, al-Fajr, says the American people “will pay the price” for the May 2 raid that killed bin Laden at a compound in Pakistan.
