A car bomb has exploded in the city of Karbala in central Iraq, killing at least 10 people and wounding dozens more, officials say.
Police said the target for the blast was a bus carrying Iranian pilgrims.
Karbala is a place of pilgrimage for Shia Muslims.
The latest attack came as Iraqi leaders were heading north to the city of Erbil in Iraqi Kurdistan for top-level meetings aimed at finalising a power-sharing deal for a new government.
Iraq has been without a government for eight months after inconclusive general elections.
The blast went off just 150 metres from the shrine of the Imam Hussein, one of the holiest sites in Shia Islam.
