More than 140 people have been killed in ethnic riots in the capitol of China's Xinjiang province. The riots began on Sunday when Uighurs, the muslim ethnic minority in the region, gathered to protest clashes that happened in June between Uighur and Han Chinese workers where 2 were killed and 118 injured. The violence brings up memories and comparisons to the deadly Tiananmen Square protests in 1989. Below are two images reflecting the comparison — the first is a picture from the current riots of elderly woman standing up to security forces. The second is an iconic image a lone man standing up defiantly to the line of tanks during the Tiananmen Square protests.
