One noteworthy event is the Feb 1997 riots in Yining, a county which is located between Kazakhstan and Xinjiang, during which 12 independence movement leaders were executed and 27 others were arrested and incarcerated. Moreover, almost 200 Uyghurs were killed and over 2,000 more Uyghurs were arrested. In 2008 riots broke out within Tibetan regions such as Lhasa, and anti-Han "pogroms" were committed in Ürümqi, Xinjiang in July 2009. In response to these riots, the Chinese government has increased its police presence in these regions and it has also sought to control offshore reporting and intimidate foreign-based reporters by detaining their family members.
