An official newspaper said an alleged attempt to crash a Chinese airline during a domestic flight last week was an act of terrorism organized by a still unnamed group, adding to signs of new volatility in the restless western regions of the country. The Global Times said Thursday that a 19-year-old woman from western China's Turkic Muslim Uighur minority group had been seized after trying to set a fire in a bathroom aboard the China Southern flight on Friday. "This was a well prepared, meticulously planned, tightly coordinated, terror attack activity," the paper reported, quoting an unidentified official with knowledge of the investigation. Police were investigating the "terrorist organization backing her," the report said. No damage or injuries have been reported in the incident.
