(CBS NEWS) A wave of bombings tore through Iraq on Tuesday, killing 65 people on eve of the 10th anniversary of the U.S.-led invasion and showing how unstable Iraq remains more than a year after the withdrawal of American troops.

It was the deadliest day of attacks in Iraq since Sept. 9, when insurgents unleashed an onslaught of bombings and shootings across the country that left 92 dead.

Violence has ebbed sharply since the peak of Sunni-Shiite fighting that pushed the country to the brink of civil war in 2006-2007. But insurgents maintain the ability to stage high-profile attacks while sectarian and ethnic rivalries continue to tear at the fabric of national unity.
