US airstrikes hit pro-Iranian militia in Iraq
The US Air Force went into action in Iraq over the weekend. But the target was not ISIS, it was an Iraqi militia group allied closely with Iran. The strikes were in retaliation for an attack on a US base that left a US contractor dead, and four military personnel wounded. Host Carol Hills speaks with Iraq veteran John Spencer, now the chair of the urban warfare studies department at the Modern War Institute at the US Military Academy at West Point, New York.
