South Korea has said that 300 of its nationals detained during the immigration raid would be flown home. Key US politics stories from Sunday 7 September at a glance

Donald Trump has told foreign companies that they must hire and train American workers and respect immigration laws, after a raid at a Hyundai Motor manufacturing facility in Georgia saw about 300 South Koreans detained.

Nearly 500 workers in total were detained in the raid on Thursday, with US authorities releasing footage showing them restrained in handcuffs and ankle chains, loaded on to buses.

The raid marked the largest single site sweep carried out under Donald Trump’s nationwide anti-immigration campaign and appeared to strain the longstanding diplomatic and economic relationship between the US and South Korea.

“I am hereby calling on all Foreign Companies investing in the United States to please respect our Nation’s Immigration Laws,” Trump wrote on Truth Social on Sunday, adding “Your Investments are welcome, and we encourage you to LEGALLY bring your very smart people … What we ask in return is that you hire and train American Workers.”
