A Sichuan soldier was attacked outside army barracks last Thursday, just a week after another soldier was shot dead in neighboring Chongqing.
The soldier was stabbed in the back outside the barracks in Leshan, Southwest Sichuan province, a police source said.
A senior police official in Leshan told China Daily yesterday on condition of anonymity that the attack might be connected to Tibetan separatists, without giving the reason.
The Leshan barracks and the army barracks in Chongqing both belong to the same division of the People's Liberation Army (PLA).
"If the two attacks are linked, they are definitely terrorist attacks," said the source.
"The terrorists' purpose is to attract international attention as some Westerners still think the PLA entered Tibet to suppress, not to liberate."
He said that around 3 am on Thursday, the assailant jumped the wall of the soldiers' dependents' residential section.
When the assailant was walking out of the gate he stabbed the soldier from behind several times and then ran away, the official said.
Since the attack, every sentry at military camps in Leshan had been equipped with a rifle fitted with bayonet and pistol, he added.
In other developments, Qinghai police refuted Western media reports that yesterday's siege of a city police station by dozens of people was related to Tibet.
The suspects who attacked a police station and injured two officers in the capital city Xining, northwestern Qinghai province, yesterday morning were not Tibetans, an official said yesterday.
"The incident has nothing to do with Tibetan separatists. The suspects are Henan people," Li Weijun, spokesman for the Xining public security bureau, told China Daily yesterday after overseas media hinted in reports the incident had something to do with Tibetans.
Li Weijun said the attack was related to a quarrel between two households.
At 12:45 am on Sunday, the bureau's 110 command center received a call from a local resident who reported his upstairs neighbors, tenant Li Zuchao and five other people, had beaten him when he asked them to fix the water leak in his room, the official said.
Li Zuchao and his fellows, all drunk, beat the complainant and his friend, injuring their heads and hands, Li Weijun said. Two policemen from downtown's Hutai police station were dispatched to solve the quarrel, but Li Zuchao and his accomplices beat the officers when they arrived. The policemen then took Li and the others to the station.
However, Li Zuchao called 30 to 40 of his Henan friends who staged a siege at the police station.
A local special police team dispersed the mob but two police officers received ear and foot injuries.
"The two policemen are still at Xining Red Cross Hospital for treatment," he said.
The police detained seven people, including Li, for questioning and the incident was under investigation, he said.
