A senior Afghan official says there is evidence that the leader of the Taleban, Mullah Omar, is still alive and inside Afghanistan. Ahmad Wali Karzai, the brother of President Hamid Karzai and his special representative for the south of the country, said there were regular sightings of the cleric and a small group of followers. He said they appeared to be constantly on the move and had been seen in various places including Zabul province in the south-east, central Uruzgan province and the south-western region of Helmand. Mr Karzai said there had been no sighting of Osama Bin Laden and it was still not known if he was dead or alive. (BBC)
