The protest near the White House was among the demonstrations that erupted across the country after Israel and the United States launched strikes on Iran.

The demonstration at the Lincoln Memorial was the latest in a string of school walkouts across the country, which have resulted in arrests and condemnation from some officials, and plaudits from others.

Protesters calling for the release of political prisoners in Azerbaijan told CNN they were attacked by security guards protecting the country’s President Ilham Aliyev in Washington, DC on Thursday following President Donald Trumps’s inaugural Board of Peace meeting.
