CNN has apologized for a misleading headline that appeared on its website during its coverage Sunday of the Hong Kong riots.

At one point, a headline reading “Police Use Petrol Bombs and Water Cannons Against Hong Kong Protesters” flashed on the screen.

According to Hong Kong police, officers shot water cannons at barricades, not people, and it was the demonstrators who threw the gasoline bombs.

CNN’s Hong Kong bureau chief Roger Clark admitted in a letter to police that the headline was “erroneous.”

Clark said CNN is “working hard to ensure that reporting of the Hong Kong protests is fair and balanced at all times.”
