Pentagon: Iran launches more than a dozen ballistic missiles at 2 Iraqi bases
The Pentagon confirmed that Iran launched missiles at US military and coalition forces in Iraq.
The Pentagon said Iran fired more than a dozen missiles.

The bases, he said, have been on high alert "due to indications that the Iranian regime planned to attack our forces and interests in the region."
