'You dropped bombs on Iraq’: Colin Powell heckled by protester on live TV (VIDEO)

Former US Secretary of State, Colin Powell, was heckled during a live interview on CBS by a angry off-screen protester venting his ire over the Iraq war.

Powell was speaking on CBS This Morning about the Smithsonian’s new National Museum for African American History and Culture when a protester loudly interrupted the interview. Calling from off-set, the man shouted, “You know better, Colin Powell, as a black man in America...you dropped bombs on Iraq.”

Powell seemed unfazed by the incident and quipped to the reporters, “Is he one of yours?”

The show’s presenters appeared more shaken by the incident than Powell, with online observers noting the fearful reaction of co-anchor Gayle King in particular.

Powell, who served as Secretary of State under George W. Bush during the 2003 invasion of Iraq, recently came into the spotlight again after emails revealed he advised his successor Hillary Clinton to use a private email server - an issue some viewers thought should have been prominent in his CBS appearance.

In the build up to the Iraq war, Powell alleged in 2003 during a speech to the UN Security Council that Iraq was hiding weapons of mass destruction. However, after the US invasion and overthrow of Saddam Hussein, no nuclear or chemical weapons were found.

In 2004 and 2005,Powell acknowledged that much of his 2003 UN presentation was inaccurate.

Powell has previously admitted that the Bush administration made "terrible strategic mistakes" during the Iraq War but defended the decision to invade, claiming they were unaware their intelligence was faulty.
