t's one of three cases he is fighting in the courts since returning home last month after four years in self-imposed exile.

His arrest and disqualification from contesting elections on May 11 have been a humiliating blow for the former ruler of nuclear-armed Pakistan, previously a key ally of US president George W. Bush in the war on terror.

Despite a heavy police and paramilitary presence, scuffles broke out between lawyers and Musharraf supporters, who threw stones and beat each other with sticks outside the court building.

About 150 lawyers shouted: "Dog, dog, Musharraf dog!" while two dozen supporters chanted "Long live Musharraf!"

"Today it was routine hearing of Benazir murder case and General Musharraf appeared for the first time in this case," said his lawyer Salman Safdar.

Musharraf spent around 15 minutes in court and then another 15 minutes with his lawyer, before being driven back to his home.

Nobody has been convicted or jailed for Bhutto's assassination on December 27, 2007, in Rawalpindi, despite a long-running court case.

In November 2011, the court indicted two police officers and five alleged Taliban militants over her assassination.

In August 2010, it ordered the confiscation of Musharraf's property and the freezing of his bank accounts in Pakistan over his failure, while in exile, to appear to answer questions related to her death.

Safdar said that Musharraf's team asked the court to rescind those orders, given that he was now prepared to appear in court, complained that lawyers had been barred from meeting him and ordered police to investigate.
