U.S. officials say President Barack Obama has approved sending humanitarian supplies by air to thousands of religious minorities in Iraq who are under siege from Islamic militants.

But the officials say Obama has not made a final decision on whether the relief mission will be accompanied by U.S. airstrikes. Obama could announce his decisions as early as Thursday night.

The officials insisted on anonymity because they were not authorized to discuss matter by name ahead of the president.
