An Iraqi-American man has said that US President Donald Trump's ban on immigrants from several Muslim majority countries has led to the death of his mother.

Michael Hager, who originally came to the U.S. as a refugee during the Gulf War, was in Iraq with his mother visiting family. They were in line at the airport waiting to travel back to their home in Michigan. Then Hager's mother was told she would not be allowed on the plane.

She was ill and they were planning to take her to a hospital in the US so she could get better care. Despite the fact that she had lived in the US since 1995 and possessed a Green Card (permanent residency), she was forbidden from traveling to the US due to Trump's ban.

"The immigration told us that the president of the United States put an order right now - you guys cannot go," Hager told FOX 2.

He said his mother knew "right there if we send her back to the hospital [in Iraq] she's going to pass away - she's not going to make it."

Hager's mother returned to the hospital in Iraq and died. Hager returned to Michigan alone. He was allowed to travel because he is an American citizen.

Hager worked for the US military as a contractor between 2003 and 2008 – serving as an interpreter and cultural advisor. 

He now blames Trump personally for the death of his mother.

"I really believe this in my heart: if they would have let us in, my mom - she would have made it and she would have been sitting right here next to me," Hager said. 

"She's gone because of him."

Many other families have been torn apart due to the Muslim ban, which currently targets refugees and immigrants from Iraq, Syria, Iran, Libya, Somalia, Sudan and Yemen.

A very sick refugee baby boy has been separated from his parents. At the age of one and a half, the boy, named Dilbreen, was badly burned when a heater exploded in his family's refugee tent in Iraq.

An aid group managed to get emergency visas for Dilbreen and his father to travel to the US, so the baby could be hospitalized in Boston. After Dilbreen underwent preliminary surgery, his father traveled back to Iraq to be with his wife as she gave birth to another child.

The whole family was planning to travel to the US to be united with their son. But now their visas have been revoked.

"So they are stranded in Iraq," an activist told CBS Boston. “The child is here. The need for surgery is pressing.”
