The flight appeared to be the first use of an American military aircraft to deport people to India, which is one of the top sources of illegal immigration to the United States.

The US began deporting the first batch of undocumented Indian migrants since President Donald Trump returned to office threatening trade action against countries who didn’t comply with his immigration policies.

The United States is rigorously tightening immigration laws, the American embassy said on Tuesday amid reports that a US military aircraft is bringing some illegal migrants to India. The first round of deportation of illegal Indian nationals from the US comes around two weeks after Donald Trump became the US president for a second term.
