China鈥檚 security chief has accused a Uighur separatist group, designated a terrorist organization by the United Nations, of being behind Monday鈥檚 fiery car crash in Tiananmen Square that killed five and injured 40.聽

On the contrary, say a number of Chinese and foreign experts on security in Xinjiang. In the restive far western province where most Uighurs live, they say, it may have been the attackers鈥� very lack of ties to any organization that helped them evade the Chinese police.

Uighur radicals seeking independence from Beijing engage nowadays in 鈥渇ewer and fewer organized activities鈥� in the wake of successful government drives against them, says Yang Shu, an expert on Uighur separatist movements at Lanzhou University in western China.

鈥淭here are fewer contacts amongst them鈥�which makes it hard to collect intelligence on them,鈥� he adds.

Meng Jianzhu, China鈥檚 top domestic security official, told reporters聽during a visit to Uzbekistan Thursday that 鈥渂ehind the scenes inciting [the attack] was the terrorist East Turkestan Islamic Movement 辞谤驳补苍颈锄补迟颈辞苍.鈥�

The Chinese authorities have often blamed outbreaks of violence in Xinjiang on ETIM, claiming the group has ties to Al Qaeda and the Taliban. Washington and the UN put the group on their terrorist blacklists, at Beijing鈥檚 request, in 2002, but the United States quietly removed it amid doubts that it really existed, at least in the form the Chinese claimed.聽

鈥淢any analysts doubt there is an organized grouping that can really take on the Chinese in a concerted way,鈥� says Magnus Ranstorp, who studies international terrorism at the Swedish National Defense College.

鈥淚 think there are violent [Uighur] gangs rather than a large scale terrorist organization,鈥� adds Jiang Zhaoyong, an independent commentator who has studied Xinjiang for many years.

One notable aspect of the police account of Monday鈥檚 incident was that Usmen Hasan, identified as the driver of the car, was said to have been accompanied by his wife and mother. All three died when their SUV caught fire after crashing into the entrance to the Forbidden City.

There is precedent for Uighur family members to carry out attacks together: an uncle and his nephew drove a car packed with explosives into a squad of policemen in the Xinjiang city of Kashgar in 2008, killing 16 and injuring 16, Prof. Yang recalls.

鈥淚f family members plan these attacks over the dinner table or in bed it is very hard for authorities to learn about them,鈥� he points out.

At the same time, says Gardner Bovingdon, an expert on Xinjiang who teaches politics at Indiana University at Bloomington, the heavy police presence that blankets many Uighur communities has led to 鈥渓ots of suspicion that people you don鈥檛 know are spies. It is possible that suspicion has led people to be more circumspect鈥� and thus able to evade Beijing鈥檚 surveillance web.

Past clashes

Xinjiang, where most of China鈥檚 11 million Muslim Uighurs live, has been struck by sporadic violent incidents in recent years, according to official reports. Foreign journalists seeking to confirm them have routinely been turned away by police; many of the accounts of Uighur protest behavior offered by officials over the years have been questioned.聽

Last June, 27 people, including nine policemen, died in Shanshan, near Turpan when men armed with knives attacked a police station, the official news agency Xinhua reported. (One of the five suspects arrested in connection with Monday鈥檚 incident lived near Shanshan, according to police.)

Two months earlier, 21 people had died in a pitched battle near Kashgar between men armed with carving knives and local security officials that ended in a fire. In 2011 four policemen and 14 assailants were killed during an assault on a police station in Hotan.

Attacks in the rest of China attributed to Uighurs have been less common, though not unknown. In 1997 a separatist Uighur group based in Kazakhstan claimed responsibility for a bomb blast on a Beijing bus that killed two people and injured ten.

Though the government generally blames violence in Xinjiang on organized, religiously motivated separatists, other observers see them as more random expressions of discontent.

鈥淚n my mind they are hate crimes triggered by tensions between minority groups and the Han," says Mr. Jiang. The Han are the ethnic group that makes up 95 percent of the Chinese population.

The attack in Tiananmen Square 鈥渋s one of many manifestations of widespread and deep Uighur discontent鈥� by no means all of which are violent, says Prof. Bovingdon.

鈥淪till, if it turns out to have been Uighurs with religious motivation self immolating and taking people with them,鈥� as Chinese police say, 鈥渋t is a striking and novel strategy,鈥� Bovingdon adds.

No group has claimed responsibility for the deadly crash, nor have the police advanced any motive for the attack other than to say that they found a 鈥渏ihad鈥� flag in the place where one of the five suspects arrested on Monday had been staying.

Uighurs chafe under restrictions on their religious practice and culture and complain that they do not enjoy the same economic opportunities as the Han settlers who have flooded into Xinjiang in recent decades, making Uighurs a minority in their own region.

Those Uighurs who travel elsewhere in China in search of work say they often face discrimination in employment, housing, and treatment at the hands of the police, and often of ordinary Han. 聽

Hundreds of thousands of Uighurs have moved beyond Xinjiang鈥檚 borders, making it difficult for the police to spot malcontents who might turn to violence. 鈥淚t is impossible for the government to keep an eye on all of them, and nor would it be proper to do so鈥� since most are law abiding citizens, says Yang.

And while Xinjiang is under heavy security, 鈥渇ew provincial governments in the rest of China are very aware or well informed about anti-terrorism security,鈥� says Li Wei, a security expert at the China Institutes of Contemporary International Relations and adviser to the government.
