"Red Shirt" demonstrators on motorcycles gather for a rally to celebrate Malaysia Day and to counter a massive protest held over two days last month that called for Prime Minister Najib Razak's resignation over a graft scandal, in Malaysia's capital city of Kuala Lumpur September 16, 2015. The Malaysian government warned the Malay organisers of a mass rally getting underway in Kuala Lumpur on Wednesday to avoid racial slurs and slogans that could raise tensions in the multi-ethnic Southeast Asian nation.
