Baltimore (AFP) - The Maryland National Guard was placed on alert Monday as riots and looting broke out in the streets of Baltimore following the funeral of an African American man who died in police custody.

"Today's looting and acts of violence in Baltimore will not be tolerated. In response, I have put the Maryland National Guard on alert so they can be in position to deploy rapidly as needed," state Governor Larry Hogan said in a statement.

Baltimore's Major League Baseball team the Orioles cancelled Monday night's game against Chicago's White Sox amid rioting in the US city.

The team announced the postponement on Twitter shortly before the game was due to begin, "after consultation with the Baltimore Police Department."
