BEIJING (Reuters) - Chinese police shot dead six people during a "terrorist" attack in the restive western region of Xinjiang and six more died when explosives they were carrying detonated, state media said, as officials accused a prominent academic of aiding militants.
The police came under attack on Friday by a group throwing explosive devices in Xinhe county, the official news agency Xinhua said on Saturday, citing regional authorities, the latest violence to jolt an area with a large Muslim population.
Five suspects were captured and one policeman was slightly wounded, Xinhua said.
The Global Times, owned by Chinese Communist Party mouthpiece the People's Daily, said two explosions had occurred in a beauty salon and a grocery market in Xinhe on Friday evening.
Mr Dilxat Raxit, spokesman for the main Uighur exile group, the World Uyghur Congress, suggested that the beauty salon was a front for a brothel that had offended Uighurs "as it directly affected the Uighurs' traditional lifestyles".
"China has refused to disclose the real reason for the protests by the Uighurs," Mr Raxit said in an e-mailed statement."The forced repression and provocation is the real reason for the confrontation. The Uighurs simply cannot endure the current repressive policities pursued by China."
Xinjiang has been the theatre of numerous incidents of unrest in recent years, which the government often blames on the separatist East Turkestan Islamic Movement (ETIM), although experts and rights groups cast doubt on its existence as a cohesive group.
Around 100 people, including several policemen, have been killed in violence in Xinjiang since last April, according to state media reports.
Many rights groups say China has overplayed the threat posed by militants from the large Uighur minority, Muslims who speak a Turkic language, to justify tough controls in energy-rich Xinjiang. The region lies on the borders of ex-Soviet Central Asia, India and Pakistan.
Eleven people believed to be members of a militant group of Uighurs were killed in Kyrgyzstan after illegally crossing into the former Soviet republic from China, Kyrgyz border guards said on Friday.
The police in Xinjiang's regional capital Urumqi said on Saturday that well-known, Beijing-based Uighur economics professor Ilham Tohti was being investigated for promoting Xinjiang's independence and abetting separatists.
Prof Tohti was detained in Beijing last week, prompting concern from both the United States and European Union. He had used his classes to laud the attackers in recent militant incidents as "heroes", "inciting the students to hate the country, hate the government and seek to overthrow it", the Urumqi police said on their official microblog.
The Chinese-language statement implied a link with ETIM, but a later English translation by Xinhua did not use such specific terms.
"Ilham Tohti used his position as a teacher to entice, lure and coerce certain people to form a gang, colluded with leaders of overseas East Turkestan separatist forces, and sent followers overseas to engage in separatist activities," the statement said.
Prof Tohti also sowed misinformation and rumours and "agitated for Xinjiang independence", the police said, adding they had"cast-iron evidence" against him.
Prof Tohti's wife Guzaili Nu'er said on Sunday she thought the accusations were ridiculous.
"Do they really think the university would allow him to say such things in class? He's just an ordinary teacher. Why are they saying these things?" she told Reuters by telephone from her house, which is under close watch by police.
"And all this stuff about East Turkestan elements. What rubbish."
Ms Nu'er said she still had no idea where he husband was being detained because authorities had not told her anything and were following her every move.
Prof Tohti has championed the rights of the Uighur community in Xinjiang, and has challenged the government's version of several incidents involving Uighurs, including what Beijing says was its first major suicide attack involving people from Xinjiang in Beijing's Tiananmen Square last year.
