Protests demand release of Palestinian activist Mahmoud Khalil

Protests are set for Tuesday in major cities, including a walkout at Columbia University, demanding the release of Palestinian activist Mahmoud Khalil. He was arrested by immigration agents on Saturday and is currently detained in Louisiana. A U.S. District Judge has temporarily blocked Khalil's deportation, allowing him to remain in the U.S. while the court reviews his case. A detention hearing is scheduled for Wednesday. Khalil's attorney claims his arrest is illegal and an attack on free speech. The government alleges he has ties to Hamas, but no evidence has been provided. Protests have already begun, with demonstrators calling for his release.
