 This is Morning Edition from NPR News. I'm E. Martinez. And I'm Michelle Martin. A 72-year-old Syrian man was planning to fly from L.A. to Beirut earlier this month. He never boarded the plane. Instead, he was arrested at the airport on charges of immigration fraud. Syrian activists say he is a war criminal linked to atrocities of Bashar al-Assad's regime, and they hope his arrest is a turning point. NPR's Michelle Kellerman has this report.
