Pro-Khalistan protesters shouted slogans, threw water bottles and ink at the London Metropolitan police today, who kept them confined to the other side of the road, a safe distance from the Indian High Commission. For the protesters, the immediate provocation was the bigger Indian flag draped over the walls of India House. The High Commission employees had retaliated with a bigger flag a day after Sunday's unprecedented vandalism, when the Indian flag was pulled down and the windows of the building were broken.
