A flight carrying hundreds of South Korean workers who were detained by US immigration authorities in Georgia last week departed late Thursday morning, according to CNN Correspondent Gustavo Valdes, who witnessed the plane take off at Hartsfield-Jackson International airport in Atlanta.

South Korea says a charter plane that is planned to carry South Korean workers who were detained in an immigration raid in Georgia will depart Thursday at noon to return home.

The ICE raid that swept up 300 South Koreans in Georgia has strained an important bilateral relationship, and highlighted a significant challenge.

A South Korean charter plane departed Incheon International Airport on Wednesday bound for the United States to bring home workers detained in last week’s immigration raid in Georgia.

The Boeing 747 is expected to land in Atlanta shortly before 10 a.m., according to flight-tracking site Flightradar24.

The immigration raid has caused confusion, shock and a sense of betrayal among many in South Korea, a key U.S. ally.
