Jill Stein of the US Green Party has been arrested at a pro-Palestinian rally at Washington University in St. Louis, Missouri. Stein’s arrest came amid a nationwide crackdown on anti-Israel demonstrations.

Stein, her campaign manager, and her deputy campaign manager were among 100 people detained at a protest camp on Washington University’s campus on Saturday. Video footage shows the 73-year-old being led away from the camp by three police officers, her hands apparently bound behind her back with zip ties. 

The encampment was set up to demand that the university divest from Boeing, which manufactures arms used by the Israeli military to strike Gaza, Stein’s campaign manager, Jason Call, said in a statement.
