There have been calls for calm in the US, following Friday's court verdict that cleared a US teenager of murder.

Kyle Rittenhouse, 18, had argued he was acting in self-defence when he shot dead two men and injured a third during racial unrest last year.

The not-guilty verdict has deeply divided the country.

Calls for calm have come from officials and also families of the victims, whose lawyers said what is needed now is "justice, not more violence".
