Protests in March, 2008 developed into riots in which Tibetan mobs attacked Han and Hui people in Lhasa. The Chinese government reacted curtly, imposing curfews and pressuring journalists in Lhasa to leave the region. The international response was measured, with a number of leaders expressing concern. Some people protested in large European and North American cities and chanted slogans, with some supporting China's actions and some supporting the protesters in Tibet.
