President Bush demanded Thursday that those responsible for the killing of former Prime Minister Benazir be brought to justice.
"The United States strongly condemns this cowardly act by murderous extremists who are trying to undermine Pakistan's democracy," he said. "Those who committed this crime must be brought to justice."
The president was speaking to reporters at a hangar adjacent to his Crawford ranch in central Texas.
Bush expressed his deepest condolences to Bhutto's family and to the families of others slain in the attack and to all the people of Pakistan.
"We stand with the people of Pakistan in their struggle against the forces of terror and extremism. We urge them to honor Benazir Bhutto's memory by continuing with the democratic process for which she so bravely gave her life," he said.
Bush looked tense in delivering a statement that lasted about a minute and he took no questions.
President Bush is making a televised statement as I type, and we'll have that for you as well.
