NEW YORK (AP) - U.S. officials say Pakistan is quietly consulting with other nations about its investigation into Benazir Bhutto's assassination.
Bhutto's aides are alleging a cover-up in the former prime minister's death and uncertainty about her manner of death is setting in.
She was killed after a suicide attacker shot at her and then blew himself up outside a campaign rally Thursday.
Authorities initially said she died from bullet wounds. Later, a surgeon said shrapnel killed her. But the Interior Ministry now says Bhutto was
killed when she smashed her head into the sunroof.
With mounting pressure to sort through the discrepancies, Pakistan is publicly insisting it doesn't need foreign help in its investigation.
A senior U.S. official says the Pakistani government is asking other governments "how best the investigation can be handled."
A U.N. official tells The Associated Press, the Pakistanis "don't want the U.N. involved" in the inquiry.
Pakistan's Interior Ministry spokesman says he thinks the country is "capable of handling" the investigation.
