Due to the violence on the streets of Baltimore, the city has issued a state of emergency and National Guard troops have been deployed there.

Overnight, a number of fires have been reported and Baltimore police have reported the people have thrown cinder blocks at fire engines when the firefighters were working to extinguish the flames.

There will be a citywide curfew in effect from 10 p. m. on Tuesday until 5 a. m. Wednesday. Mayor Stephanie Rawlings-Blake said that the 10 p. m. curfews will last for seven days, and could be extended if in need. A 9 p. m. curfew has been in effect for children 14 and under. Rawlings-Blake said that this is not a lawless city.

Today, all Baltimore City Public Schools will be closed, and a Baltimore Orioles-Chicago White Sox baseball game could be moved.

In a news conference, Police Commissioner Anthony Batts said during Monday's violence, fifteen officers have got injured, out of which six have received series injuries, though they are not expected to be life-threatening.

He said that this is neither protesting, nor your First Amendment rights. This is called criminal acts.

The Baltimore Police Department said that Monday's standoff started near the Mondawmin Mall in the northwest part of the city, when the group threw bricks, rocks and other objects at the officers.

It said that the protesters climbed on a police cruiser and damaged many others, and fires broke out, in which a community center project was also engulfed in flames.

The unrest sparked off due to the death of Freddie Gray, who died after being in police custody. While speaking on the night of the 25-year-old's funeral, Gray's mother made a plea for peace.

Late Monday, while talking to the reporters, Rawlings-Blake decried the violence and property damage. Rawlings-Blake said, "People say they care about their community and want to be heard, but you can't care about your community and do what they did".
