Pakistan’s former military ruler Pervez Musharraf has been named as the prime suspect in the assassination of ex-prime minister Benazir Bhutto.

Officers with the Federal Investigation Agency named Musharraf in court documents, according to a McClatchy report.

Musharraf already faces a possible charge of high treason. On Monday, Prime Minister Nawaz Sharif said he was considering whether to level the charge, based on Musharraf’s decision to declare a state of emergency and suspend the constitution in November 2007.

"Musharraf has to answer for all his deeds in court," said Sharif.

Musharraf ousted Sharif in a military coup in 1999 and ruled the country until 2008.

Bhutto, who had lived in exile for nine years, died shortly after returning to Pakistan in October 2007 during the parliamentary elections.

The elections had been put into question after Musharraf declared a state of emergency on Nov. 3, 2007, citing the country’s growing instability from terrorist attacks.

On Dec. 27, 2007, Bhutto died after a political rally when a gunman opened fire and detonated a bomb.

Another 24 people were killed in the attack.
