Pakistani former Prime Minister Benazir Bhutto has been assassinated in a suicide attack.
Ms Bhutto - the first woman PM in an Islamic state - was leaving an election rally in Rawalpindi when a gunman shot her in the neck and set off a bomb.
At least 20 other people died in the attack and several more were injured.
President Pervez Musharraf has urged people to remain calm but angry protests have gripped some cities, with at least 11 deaths reported.
Pervez Musharraf 总统呼吁民众保证镇静，但是愤怒的抗议者们包围了部分城市(滋事)，相继有11起死亡报道。
Security forces have been placed on a state of "red alert" nationwide.
There were no immediate claims of responsibility for the attack. Analysts believe Islamist militants to be the most likely group behind it.
Ms Bhutto, leader of the Pakistan People's Party (PPP), had served as prime minister from 1988-1990 and 1993-1996, and had been campaigning ahead of elections due on 8 January.
It was the second suicide attack against her in recent months and came amid a wave of bombings targeting security and government officials.
