Minnesota Governor Tim Waltz on Thursday called on the National Guard to rule out raging protests in the state’s largest city, Minneapolis.

The protests continued for the third day. They originated when black George Floyd died in an arrest on Monday.

The video, filmed by an eyewitness, showed how Caucasian police kept their knees on Floyd's neck for about eight minutes until he lost consciousness.

Most of the protesters performed calmly, but some escalated into riots. The Twin Cities Pioneer Press reported that people broke shop windows, robbed shops and threw rocks and bottles at police. Several movements were set on fire.

A MSNBC television broadcast showed police firing tear gas at around 9 pm local time against protesters gathered in front of the police station. At about 10:25 p.m., the police station caught fire, and the crowd cheered.

Mall of America, the largest mall in the United States in Bloomington, a suburb of Minneapolis, was closed due to riots. It was still closed to customers due to the coronavirus, but several stores had staff preparing for reopening.

Several other malls and stores also closed their doors.

Protesters protesting Floyd’s death also gathered in several other cities across the United States.

The police officers involved in Floyd’s arrest have been fired and are all under criminal investigation. Justice Minister William Barr has called the investigation a “high priority”.
