The State Department has evacuated nonessential personnel from the U.S. embassy in Port-au-Prince, Haiti as the security situation continues to deteriorate, a report said Sunday.

U.S. Marines were also flown into the capital to help reinforce defenses at the embassy, according to a statement by the U.S. Southern Command reported on by several news outlets.

"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 statement said, according to the Miami Herald.

Armed gangs have been rampaging across the metropolitan area and reportedly control more than 80% of the capital.

In many cases, nonessential personnel can include the families of diplomats, but the embassy had already ordered departure for nonessential staff and all family members in July, the Associated Press reported.

As the statement noted, "No Haitians were on board the military aircraft." There are concerns that senior government officials are trying to flee the country.

Haiti has been in a state of emergency since March 3.
