Thai pro-democracy protesters were confronted by riot police and water canons on Sunday as they tried to approach Bangkok’s Grand Palace to deliver letters about their political grievances addressed to the country’s king.

The protesters had pushed aside a bus that was serving as a barrier to try to get closer to the palace, which houses the royal offices.
