LINCOLN, Neb. (AP) — Hundreds of people marched through downtown Lincoln and converged at the Nebraska governor’s residence to plead for help for a religious minority group in northern Iraq.

Two people were arrested for allegedly attacking officers on Sunday. No injuries were reported, and the group dispersed later in the afternoon.

Protesters were met by Lincoln police and Nebraska State Patrol troopers, who had at least 20 vehicles at the scene. The Nebraska Capitol across the street was temporarily closed and locked.

The protesters were pleading for help for Yazidis, a religious minority group, in northern Iraq and Syria. Militants with the Islamic State extremist group seized two small towns in northern Iraq on Sunday after driving out Kurdish security forces.
