The American people celebrated throughout the night the news delivered by US President Barack Obama that Al-Qaeda founder and leader Osama Bin Laden has been killed by US forces in Pakistan.

Crowds gathered outside the White House in Washington DC, chanting "USA, USA" after the news emerged. What began as a small group of students who started to gather at the fence on the north side of the White House, quickly turned into a sea of people, and later turned into a huge party.

The White House has announced late last night President Barack Obama is going to deliver an emergency address to the nation.

The address will be aired on all TV channels.

The subject of the address remains unknown with FOX News speculating it would involve the faith of Libyan leader Muammar Gaddafi and CNN citing later a White House source, saying the address will have nothing to do with Libya.

CNN further say Obama's words would be important not only for the US, but for the world.

In the aftermath of the killing of the Al-Qaeda leader, the US has issued an alert to its embassies around the world, warning Americans of the possibility of al-Qaeda retaliation attacks.

"The fight against terror goes on, but tonight America has sent an unmistakable message: No matter how long it takes, justice will be done," former US President George W. Bush is quoted saying

Former US President Bill Clinton also issued a statement:

"This is a profoundly important moment not just for the families of those who lost their lives on 9/11 and in al-Qaeda's other attacks but for people all over the world who want to build a common future of peace, freedom, and cooperation for our children," the statement reads.
