From there, he travelled to Bonn to report live on the Afghan leaders' meeting to sign a power-sharing agreement.
Brian has also reported from the Middle East in the aftermath of the attack on Yasser Arafat's headquarters and The Hague where he has presented several BBC World television news specials on the Milosevic trial.
He is currently one of the presenters of The World the BBC's daily current affairs programme which is transmitted internationally on BBC World television and domestically on BBC Four.
