Pakistan will ask Interpol to arrest ex-President Pervez Musharraf for his failure to prevent the assassination of former Prime Minister Benazir Bhutto, the interior minister said Tuesday, February 21, according to AP.

Rehman Malik said the government was seeking Musharraf's arrest because he allegedly failed to provide adequate security for Bhutto, who was killed in a gun and suicide bomb attack in 2007.

Musharraf, a one-time U.S. ally, went into self-exile in Britain in 2008 after being forced out of the presidency he secured in a 1999 military coup. The current government is being run by Musharraf's political rivals, and the president is Bhutto's widower.

Musharraf, who wants to return to Pakistan to contest elections likely this year, told a local television channel that the government was playing politics over the case. Musharraf has repeatedly denied any legal responsibilty for the killing.

A Pakistani court issued an arrest warrant for Musharraf last year over the allegations.

Legal expert Hashmat Habib said Interpol has the right to detain Musharraf and hand him over to Pakistan if it chooses to issue a warrant. But it is unclear how the international police organization will respond, or indeed whether Malik will go ahead with his threat.

The former prime minister was killed on December 27, 2007, shortly after returning to Pakistan to campaign in elections Musharraf agreed to allow after months of domestic and international pressure.
