Amir Amiri, an American citizen detained nine months ago in Afghanistan, was released Sunday and is on his way back to the United States, Secretary of State Marco Rubio announced. "Today we welcome home Amir Amiry, an American who was wrongfully detained in Afghanistan," wrote Rubio in a social media post. After the Taliban took control of Afghanistan in 2021, Qatar signed an accord to represent U.S. interests in the country. Before Amiri, it had helped secure the release of four other American citizens from Afghanistan earlier this year. Qatari diplomats monitored Amiri's health and maintained close communication with U.S. officials throughout his detention, the source told CBS News.
