Iraqi police say a suicide car bombing at a police training center in the southern city of Nasiriyah has killed at least one policeman and wounded more than 20 other people.
Word of Monday's attack came after U.S. military officials said at least 10 civilians were killed and three others wounded in an explosion Sunday in a market south of Baghdad.
The military says it is investigating what caused the explosion that rocked a candy store and other shops in the town of Iskandariyah.
In another development, Iraq's judicial authorities adjourned the trial of ousted dictator Saddam Hussein until at least Wednesday.
Saddam and some co-defendants were thrown out of court Sunday after Saddam's co-defendant half-brother cursed the court and was then dragged away by guards. Several defense lawyers walked out in protest.
