Islamabad. Pervez Musharraf, Pakistan’s former military ruler, has been charged with murder of former Prime Minister Benazir Bhutto, who died in a gun and bomb attack in December 2007, court officials say.The case of Bhutto’s murder is one of several that Musharraf is facing since his return from self-imposed exile earlier this year. "He was charged with murder, criminal conspiracy for murder and facilitation for murder,” public prosecutor Chaudhry Azhar said at the anti-terrorism court in Rawalpindi hearing the case on Tuesday.Musharraf, 69, who attended court proceedings amid high security, denied the charges and the case was adjourned until August 27.Six other people, including two senior police officers, are also facing charges in the case. Bringing charges against a former army chief is an unprecedented move in a country ruled for more than half of its history by the military.The decision by a court in Rawalpindi marks the first time Musharraf, or any former army chief in Pakistan, has been charged with a crime.Musharraf seized power in a bloodless coup in 1999, and was forced out by a democratically elected government in 2008.He has been under house arrest at his villa on the edge of the capital Islamabad since April 19, when he returned ahead of a general election to begin campaigning for his All Pakistan Muslim League (APML) party.Musharraf’s legal team dismissed Tuesday’s indictment."These charges are baseless. We are not afraid of the proceedings. We will follow legal procedures in the court,” his lawyer Syeda Afshan Adil said. A large contingent of security forces guarded the area around the court in Rawalpindi, the city where Bhutto was killed while leaving a public rally on December 27, 2007, with roads sealed off for Musharraf’s appearance.
