More than a dozen people were arrested on the third day of the Republican convention as protesters clashed with police.

17 arrests were made on Wednesday, bringing the total number over the past three days to 22.

Two police officers also reportedly received minor injuries.

Police in black riot gear and mounted on horses were deployed to the streets of Cleveland, Ohio, where the convention is taking place.

Tensions rose further after protesters burned an American flag, and police hurriedly put out the flames.

Most of the protesting has occurred in Public Square, close to the convention arena. They were given orders to dispense but some refused.

Clashes happened between protesters themselves.
