Islamabad: The Pakistan government has informed a court that it cannot extradite former President Pervez Musharraf in connection with a case registered over the killing of Baloch nationalist leader Akbar Bugti in a military operation in 2006.

Deputy Attorney General Malik Sikandar informed the Balochistan High Court during a hearing of the case in Quetta that the Interior Ministry had concluded it would not possible to extradite Musharraf, currently living in Britain in self-exile.

Sikandar on Thursday informed the two-judge bench headed by Chief Justice Qazi Faez Isa that there were five conditions rendering the extradition impossible. He did not give details about these conditions.

The court expressed its ire at the government's "lack of seriousness". The bench asked Sikandar to quit his post if he was unable to perform his duties.

Musharraf is the main accused in the case related to the killing of the Baloch leader. The federal government had earlier sought more time from the court to prepare a response on its efforts to extradite Musharraf.

Bugti was killed during a military operation against Baloch nationalist rebels in 2006 that was ordered by Musharraf, who was then also the army chief.
