The mayor of Kabul, Mir Abdul Ahad Sahebi. who has been convicted of corruption, refuses to resign.

Earlier this week he was sentenced to four years in prison. He has appealed against his conviction.

Police and the Public Prosecutor both say they do not have the authority to arrest the mayor.

Sahebi is the first Afghan leader to be convicted of corruption since the re-election of President Hamid Karzai.

Western governments have urged the president to take steps to deal with the huge problem of corruption in his country.
