In recent months Iraq has had its worst wave of violence in years. This month, more than 300 people have been killed, according to the Interior Ministry.

In Karbala, just before Muslims were breaking their Ramadan fast in the evening, a blast near a downtown market killed 9 people and wounded 22 others.

Earlier in the day, 11 people were killed and 68 were wounded in Kut, southeast of Baghdad, when a bomb exploded while they were shopping in a market, officials said. When the provincial governor visited the site after the explosion, angry bystanders threw stones and shoes at him.
