Pakistan will speed up its own inquiry into the killing of Benazir Bhutto, the former prime minister.
A UN report on her assassination has already concluded that her death could have been prevented.
It accuses the former and present government, of not providing her with adequate security.
Bhutto was killed in Rawalpindi in December 2007, while campaigning for national elections.
Kamal Hyder reports from Islamabad.
