喀什 (Kashi or Kashgar / Kāshí) and 库车 (Kuqa / Kùchē) are Chinese cities, both located in Xinjiang province, home to a large percentage of China’s Muslim and Uyghur population.
Why it is blocked: On August 4, 2008, sixteen Chinese police officers were killed in Kashgar. Though there are conflicting reports, it was reported by state media that two terrorists drove a truck into a group of officers then attacked them with grenades and machetes. The gruesome attack, just days before the start of the Beijing Olympics, drew wide attention, with some pinning the blame on Xinjiang separatists.
Six days later, violence rocked another Xinjiang city, Kuqa. Again, Xinjiang sepratists were blamed, with several committing suicide while detonating their bombs.
Kuqa has been blocked since at least November; Kashgar’s block is more recent and clearly related to the rioting on Tuesday that left 12 dead, just the latest in a number of incidents in the region.
