KABUL: More than 2,000 Afghans are rallying on the last day of a Shia Muslim holiday to mourn and denounce Pakistan for the deadly bombing at a shrine in Kabul that killed 56 and wounded more than 160 people.

The crowd gathered Friday on the west side of Kabul on the last day of Ashoura. The holiday commemorates the death in the seventh century of Imam Hussein, the Prophet Muhammad's grandson. His death in a battle outside Karbala in Iraq sealed Islam's historical Sunni-Shiite split.

The protesters are denouncing Tuesday's suicide bombing in Kabul. It was the first major sectarian attack in Afghanistan since the fall of the Taliban regime a decade ago.

Some of the speakers at the rally blamed neighboring Pakistan for the bombing.
