The NY Times reports:
An attack on a political rally killed the Pakistani opposition leader Benazir Bhutto near the capital, Islamabad, Thursday. Witnesses said Ms. Bhutto was fired upon at close range before the blast, and an official from her party said Ms. Bhutto was further injured by the explosion, which was apparently caused by a suicide attacker. [...]
At least a dozen more people were killed in the attack.
CNN reports that President Bush condemned the attack from his ranch in Crawford, and that Pakistan President Pervez Musharraf has called an emergency cabinet meeting. A State Department spokesman said the administration “certainly” condemned the attack on the rally, adding, “It demonstrates that there are still those in Pakistan who want to subvert reconciliation and efforts to advance democracy.”
UPDATE: The Washington Wire has more.
