Chinese paramilitary police armed with assault rifles ride in trucks during a 'show of force' ceremony in Urumqi after a series of terrorist attacks recently hit Xinjiang Province, on June 29, 2013. Armoured vehicles, personnel carriers and other support vehicles blocked access to streets in Xinjiang's capital Urumqi, where paramilitary units carried out an exercise. The exercises come ahead of the fourth anniversary on July 5 of riots, between members of China's mostly Muslim Uighur ethnic minority and the Han majority group, which left around 200 dead.
