Pins and needles

Here’s some scary new terrorism...of sorts.   Gangs roaming the North western Chinese city of Urumqui have stabbed, allegedly, hundreds of ethnic Han Chinese with hypodermic needles.  Over 476 people have sought treatment. The attacks seem to be racially motivated, therefore I assume the gangs are ethnic Uighurs, continuing some sort of separatist activity. Xinjiang has a high rate of AIDS cases, although there is no specific suggestion as yet that the stabbings are an attempt to infect or inject material of some sort.  Fuller report here.   Tension is rising between the Han and the Uighur groups, with the Han venting their anger against the government in protest marches.
