BLOOMINGTON, Minn. (AP) - Demonstrators chanted "Black lives matter" as they converged in the Mall of America rotunda Saturday for a rally to protest police brutality.

The group Black Lives Matter Minneapolis had more than 3,000 people confirm on Facebook that they would attend the peaceful protest.

Official attendance figures weren't immediately available, but pictures posted to social media by local news organizations showed the rotunda was full.

The Mall of America enhanced security, and police in riot gear were present.

Stores were reportedly closed for a short time. There were no immediate reports of arrests.

After a final warning to disperse, the protesters began leaving the mall.

The rally is part of protests happening nationwide after officers weren't charged in the deaths of unarmed black men in Missouri and New York.
