Three suicide bombs ripped through a Shi'ite Muslim religious procession in the eastern Pakistani city of Lahore, killing at least 25 people and wounding at least 150.
Police said the explosions appeared to be the latest in a string of attacks by Sunni extremists against the minority Shi'a, whom they consider infidels.
Khusro Pervez, the top administrative official in the city, said the bombs exploded at three separate sites as 35,000 Shi'a marched through the streets of Lahore in their traditional mourning procession for the caliph Ali, one of Shi'ite Islam's most respected holy men.
He said six bodies had been brought to the morgue and 88 people had been hospitalized, but he warned the number of dead could rise.
After the blasts, the marchers erupted in fury and set fire to a police station and at least one police truck.
Prime Minister Yousuf Raza Gilani condemned the blasts in a statement and said the attackers would not escape justice.
