It was a bloody Christmas for American military personnel in Iraq, as they came under attack from Iran-backed militias.
A drone attack injured 3 US personnel at Erbil airbase.
Responsibility for the attack was claimed by Kataib Hezbollah and some affiliated groups.
Hours later, American forces launched retaliatory strikes at three sites allegedly linked to the group.
US Defense Secretary Lloyd Austin said that President Joe Biden had ordered the strikes.
