At least 30 people have been killed in three bomb attacks in Afghanistan.
The first was a suicide bombing at a Shia shrine in the capital Kabul as hundreds of worshippers gathered to mark a holy day.
More than 20 people died in the blast, but authorities said the number is expected to rise.
Provincial deputy police chief Abdul Raouf Taj said the explosion happened as a convoy was driving down a road, shouting in celebration of the Shia Muslim holiday of Ashoura.
Around the same time, at least four people were killed after a bomb strapped to a bicycle exploded near a mosque in the northern city of Mazar-e-Sharif.
Reports said that blast had also targeted Shia Muslims.
"It was an explosion not a suicide bombing. It was some explosives hidden in a bicycle," said Lal Mohammad Ahmadzai, a police spokesman for northern Afghanistan.
In a similar scenario, a bomb placed in a motorcycle was detonated in the southern city of Kandahar.
However, officials said the blast did not happen near any mosque or shrine.
Ashoura marks the death of Imam Hussein, the grandson of the Prophet Muhammed.
