Iraqi authorities say twin bombings Sunday near Baghdad have killed at least two people and wounded several others, one day after attacks killed more than 30 people.

The latest violence took place in the town of Madain, just southeast of the capital.

A series of explosions and shootings Saturday killed at least 31 people, many of them Shi'ite pilgrims.

The deadliest attacks happened in Baghdad where an explosion at an open-air market and a bus station killed more than 15 people and wounded dozens more, many of then women and children.

The wave of deadly attacks has shattered the peace in Iraq during the Eid al-Adha holiday.

There have been no claims of responsibility for the attacks.

Sunni insurgents and al-Qaida militants have previously targeted Shi'ites in a bid to stir up sectarian strife in Iraq.

Violence across Iraq is down sharply from its peak in 2006 and 2007. However, 365 people were killed in unrest in September, making it the country's deadliest month in two years.
