China announced the breakup of a bomb-making plot in the volatile western region of Xinjiang on Wednesday, an apparent indication that authorities had not only failed suppress the ethnic hatreds there but that the weapons of choice in the feud could be getting more lethal.
The announcement, from the Public Security Ministry, said the authorities had arrested six people who had established three bomb-making workshops and assembled about 20 explosive devices in a town 430 miles outside the region’s capital, Urumqi.
The ministry said the suspects had planned to plant the explosives on cars, motorcycles and people, but were foiled by what it called timely arrests. The police did not identify the ethnicity of the suspects. But the names suggested they were Uighurs, an ethnic group that dominated the province before an influx in recent decades of Han, China’s major ethnic group.
