BEIJING Eight suspected Islamist separatists behind a deadly attack in the Chinese capital had carried out three reconnaissance trips and collected 400 liters of fuel in preparation for their assault on Tiananmen Square, state media said.
The accused all came from Hotan in the restive far western region of Xinjiang and were hiding out in western Beijing ahead of the attack, state television said late on Friday.
They had accumulated 40,000 yuan ($6,600) and a number of knives before driving a Mercedes SUV onto the northern part of the square at midday on Monday, in front of the entrance to the Forbidden City, the report said.
The car ploughed through bystanders on the edge of the capital's iconic Tiananmen Square and burst into flames, killing the three people in the car and two bystanders, in what the government called a "terrorist attack". Forty people were hurt.
The incident has led to increased suppression of the Muslim Uighur minority in Xinjiang, according to the main Uighur exile group, who said 53 people have been arrested by Chinese armed forces for illegally hoarding religious publications as authorities step up inspections.
"Since the Tiananmen incident China has increased its local suppression and provocation of Uighurs," said World Uyghur Congress spokesman Dilxat Raxit said in email to Reuters. "It could spark a new conflict between Uighurs and China's government at any time."
Xinjiang is home to the Muslim Uighur minority, many of whom chaff at China's restrictions on their religion, culture and language, though the government says they are granted broad freedoms.
Xinjiang has been wracked by unrest in recent years, blamed by the government on the separatist East Turkestan Islamic Movement which Beijing believes was also responsible for this week's Tiananmen attack.
Rights groups, exiles and some experts say though that there is little evidence of a cohesive extremist movement operating in Xinjiang.
POLICE TRACE MOVEMENTS
State media have identified the three people in the car as Usmen Hasan, his mother Kuwanhan Reyim and his wife Gulkiz Gini, all from Hotan in the heavily Uighur southern part of Xinjiang.
The five people Beijing police have in custody are also from Hotan, according to state television. Police had previously identified another part of Xinjiang as the hometown of one of the suspects, called Lukqun.
State media said that the eight decided to set up a terrorist group in September, and seven of them arrived in Beijing by SUV on October 7, while one came by train.
On October 23, five of them returned to Xinjiang's regional capital Urumqi, while a family of three remained in Beijing.
Beijing police have said the five people it has in custody were radical Islamists who were planning a holy war. Security has been strengthened in both Beijing and in Xinjiang.
Exiled Uighur leader Rebiya Kadeer told Reuters this week that caution should be exercised over the government's account, adding she did not believe any kind of organised extremist Islamic movement was operating in Xinjiang.
Xinjiang is a sprawling, arid region that borders Central Asian nations that were part of the former Soviet Union as well as Afghanistan and Pakistan.
In 2009, nearly 200 people were killed in the Xinjiang capital, Urumqi, in rioting between Uighurs and the majority Han Chinese.
