According to police:
10:48 p.m. – Some protesters continue to stay on I-94
There are still demonstrators on I-94, 3-plus hours after the St. Paul march on the highway started.
Police have also been using marker rounds.
There are dozens of people still on the road, mostly peaceful.
10:00 p.m. – Police release smoke on crowd, officers injured
Photos and video feeds show law enforcement firing at the crowd and releasing smoke. The St. Paul Police Department explained that it's "glass balls and smoke," not gas.
Officers have also been injured.
The department previously reported that protesters were throwing objects and dumping liquids on them, and that protesters were arming themselves.
9:30 p.m. – Police tell protesters to leave or face arrest
Law enforcement on scene have been working to clear the group of protesters. According to the St. Paul Police Twitter account, police tried to negotiate with the crowd and eventually threatened and made arrests.
But the protesters haven't budged.
Photos on Twitter show buses arriving on scene. Some people in the crowd write that they're putting on goggles and masks in case tear gas is used – note, the police have not confirmed whether or not that is actually going to happen.
8:00 p.m. – Protesters block part of I-94
KSTP says hundreds of protesters have crowded Interstate 94 near Lexington Avenue in St. Paul, blocking traffic. Photographs show cars turing around on the busy road to avoid it.
Video footage posted to Twitter shows both east and westbound lanes being shutdown as the protesters form a blockade.
Law enforcement arrived on scene and – according to tweets – warned they'd make arrests. However, pictures show the group continue their march toward the officials' vehicles.
6:40 p.m. – Headed to Basilica Block Party
The group of demonstrators demanding justice for Philando Castile arrived at the gates of Basilica Block Party near the Basilica of St. Mary Saturday evening.
Video footage and photos posted to Twitter show the group coming to a halt outside of the event. They were met by police who secured the gates as demonstrators peacefully chanted and showed their signs.
5:30 p.m. – Hundreds march downtown
More than an hour after gathering in Loring Park, over 100 demonstrators took to the streets of Minneapolis, blocking traffic while carrying signs and demanding officers be prosecuted for the shooting.
The protesters marched down Hennepin Avenue – at one point, the group laid down in the streets at the intersection of Hennepin and 9th.
But video footage shows the drivers of the vehicles weren't all upset. Several showed their support for the demonstrators.
4 p.m. – The rally starts
Saturday's rally started at 4 p.m. in the Loring Park area.
