Deadly Bombing at UN Headquarters in Iraq

At least 15 people are now confirmed dead after a blast at the UN headquarters in Baghdad, Iraq. At least 40 more were wounded.

A top Pentagon official says there are reports that a suicide truck bomber rammed into the lobby of the Canal Hotel before setting off the deadly explosion. Rescue workers are now trying to free people trapped in the rubble, which reportedly includes the UN's top representative in the country.

A Syrian diplomat says the UN security council is "shocked to hear of the terrorist criminal attack" on its headquarters in Iraq. He says the UN presence in Iraq is focused on rebuilding and relief work, and that makes the attack all the more shocking.

Today's explosion comes just a day after a purported Al Qaeda tape urged Iraqi's to battle the U.S. occupation in Iraq. So far, no one has claimed responsibility for the blast.
