The president of Afghanistan has been forced to cut short a speech in front of thousands of people amid a security scare.
A bodyguard made Hamid Karzai aware of a disturbance outside the sports arena where he was delivering his address in Kabul. He was escorted to safety.
Some reports say shots were fired as a restless crowd tried to force its way in.
Chaotic scenes followed as people ran for cover, fearing an attack.
The ceremony was being held to mark the sixth anniversary of the assassination of Ahmad Shah Masood, the military leader of an anti-Taliban alliance.
He was killed in a suspected al Qaeda suicide bombing two days before the September 11 attacks on the United States.
