Pro-Palestinian protest leader detained by US officials

Mahmoud Khalil, a leader of pro-Palestinian protests at Columbia University, was arrested by immigration officers on Saturday. His detention follows President Trump's pledge to deport foreign students involved in such demonstrations. Khalil, a recent graduate and prominent protest figure, was held despite having permanent residency. His arrest has sparked a petition for his release, with thousands signing in support. Columbia University reported that Immigration and Customs Enforcement agents attempted to access campus buildings during the protests. The university stated it would comply with the law regarding law enforcement access to its facilities.
