The surge of sectarian violence in Iraq is continuing with at least 33 people killed on Thursday in yet another wave of attacks. According to the United Nations, more than 500 people were killed in Iraq this month, while more than 700 died in April, marking the bloodiest month there in nearly five years. Starting today, a ban on cars bearing certain types of license plates is in effect in the capital Baghdad as authorities attempt to stop a rash of fatal car bombings.
