HONG KONG: Hong Kong police fired tear gas Sunday to disperse a rally called over concerns about police conduct in monthslong pro-democracy demonstrations.

Organizers called the demonstration at a waterfront park but police said the rally was unauthorized and engaged in a standoff with the protesters after ordering them to leave.

Police have faced criticism for heavy-headed tactics including tear gas, pepper spray, rubber bullets and a water cannon to subdue protesters who have hurled bricks and firebombs.
