U.S.Congressman Dennis Kucinich, D-10, also responded.
"This is a very dangerous moment for the world," said Kucinich "The United States must change its policy direction in the region. It must stop adding fuel to the fire."
Bhutto was assassinated Thursday (Dec. 27) in a suicide bombing that also killed at least 20 others at a campaign rally.
The death of the 54-year-old charismatic former prime minister threw the campaign for the Jan. 8 parliamentary elections into chaos and created fears of mass protests and violence across the nuclear-armed nation, an important U.S. ally in the war on terrorism.
"Benazir Bhutto represented a courageous effort to bring principles of liberty to Pakistan. She was truly dedicated to the people of Pakistan," Kucinich added.
He had met with Bhutto several times over the years in both Washington DC and New York City.
