Hundreds of South Korean workers arrested in a surprise US immigration raid have returned home, sparking diplomatic tension between the close allies. The 475-person raid mostly targeting South Koreans at a Hyundai-LG battery plant site in Georgia left Seoul “bewildered” and warning it could impact future investment. A specially chartered Korean Air Boeing 747 flew the workers out of Atlanta following efforts to resolve the standoff. While South Korean officials confirmed the situation was settled, the Trump administration remained silent. Photos from Yonhap news agency showed the workers smiling and waving as they boarded buses after days in US detention.
