The U.S. military said on Sunday it has carried out an operation in Haiti to airlift non-essential embassy personnel from the country and added U.S. forces to bolster embassy security, as Haiti reels under a state of emergency.

"This airlift of personnel into and out of the embassy is consistent with our standard practice for embassy security augmentation worldwide, and no Haitians were on board the military aircraft," the U.S. military's Southern Command said in a statement.
