Pakistani former Prime Minister Benazir Bhutto has been killed in a presumed suicide attack, a spokesman for the Pakistan People's Party (PPP) says.
Other reports said Ms Bhutto had only been injured and taken to hospital.
Ms Bhutto had just addressed a rally of PPP supporters in the town of Rawalpindi when the rally was hit by a blast.
At least 15 other people are reported killed in the attack.
Ms Bhutto has twice been the country's prime minister and was campaigning ahead of elections due in January.
Namaz Sharif might do well to consider leaving Pakistan for his safety.
UPDATE: Al-Qaeda claims credit:
Karachi, 27 Dec. (AKI) - (by Syed Saleem Shahzad) - A spokesperson for the al-Qaeda terrorist network has claimed responsibility for the death on Thursday of former Pakistani prime minister Benazir Bhutto.
“We terminated the most precious American asset which vowed to defeat [the] mujahadeen,” Al-Qaeda’s commander and main spokesperson Mustafa Abu Al-Yazid told Adnkronos International (AKI) in a phone call from an unknown location, speaking in faltering English. Al-Yazid is the main al-Qaeda commander in Afghanistan.
It is believed that the decision to kill Bhutto, who is the leader of the opposition Pakistan People's Party (PPP), was made by al-Qaeda No. 2, the Egyptian doctor, Ayman al-Zawahiri in October.
Why am I not surprised that the leader of Al-Qaeda in Afghanistan is named Yazid?
