Al Qaeda Claims Baghdad Attacks on Shiites

BAGHDAD (AP) -- Al Qaeda's front group in Iraq has claimed responsibility for 91 deaths in a string of attacks on Baghdad's Shiite districts.

The Islamic State of Iraq is also threatening more attacks on the country's Shiite majority.

The group's statement was posted Friday on a militant website. It says the assault Tuesday on Shiite civilians at restaurants and cafes across the capital was "the first day of many bloody days to come."

The Islamic State of Iraq is an umbrella group that includes Al Qaeda in Iraq and other Sunni insurgent factions.

The group this week also threatened more attacks on Christians, after it took responsibility for a shocking siege at a Baghdad church during Sunday Mass that left 58 people dead.
