Uighur Islamic State fighters vow blood will "flow in rivers" in China

Beijing: Vowing to plant their flag in China and that blood will "flow in rivers", a video released this week purportedly by the Islamic State group shows ethnic Uighur fighters training in Iraq, underscoring what Beijing sees as a serious threat.

China is worried that Uighurs, a mostly Muslim people from western China`s Xinjiang region, have gone to Syria and Iraq to fight for militant groups there, having travelled illegally via Southeast Asia and Turkey.

Islamic State claimed responsibility for the killing of a Chinese hostage in 2015, highlighting China`s concern about Uighurs it says are fighting in the Middle East.

Hundreds of people have been killed in Xinjiang in the past few years, most in unrest between Uighurs and ethnic majority Han Chinese. The government blames the unrest on Islamist militants.

The Iraqi arm of Islamic State has released a half-hour long video purportedly showing Uighurs training, as well as some images from inside Xinjiang, including Chinese police on the streets.

One shot that shows Chinese President Xi Jinping gives way to flames in front of a Chinese flag.

"Hey, brothers. Today, we are fighting with infidels across the world. I`m telling you this: Don`t be complacent in this. Stay strong," one of the fighters says, according to Uighur speakers who analysed the video for Reuters but declined to be identified.

"We will certainly plant our flag over America, China, Russia, and all the infidels of the world," he says.

In another scene, a man chanting in Uighur says: "Our land of sharia has been constructed with spilt blood."

The video then shows pictures of people who were said to have become "martyrs" and identified as "al-Turkista¯ni¯", or men from Turkestan, the name many Uighurs use for Xinjiang.

One of the men speaking has an accent from Yarkand, close to the old Silk Road city of Kashgar in Xinjiang`s southern Uighur heartland, one of the people who reviewed the video said.

Another fighter refers to the "evil Chinese Communist infidel lackeys".

"In retaliation for the tears that flow from the eyes of the oppressed, we will make your blood flow in rivers, by the will of God," he says.

Reuters was not able to independently verify the authenticity of the video.

The video, released this week by the U.S.-based SITE Intelligence Group, which monitors militant groups online, also showed two bloody executions of unidentified people.

Chinese Foreign Ministry spokesman Geng Shuang said on Wednesday he was not aware of the video and had not seen it.

"But one point is very clear. We oppose any form of terrorism and proactively participate in international cooperation to crack down on terrorism," Geng told a daily news briefing.

"We have long said that East Turkestan forces are a serious threat to China`s security and we are willing to work with the international community to jointly crack down on East Turkestan separatist and terrorist forces," he said.

The government says foreign militants have stirred up tensions in Xinjiang, where it says it faces a determined campaign by separatists who want to establish an independent state called East Turkestan.

However, many rights groups and exiles doubt the existence of a coherent militant group in Xinjiang and say Uighur anger at repressive Chinese policies is more to blame for the unrest.

China denies any repression in Xinjiang.

The official China Daily newspaper said in an editorial on Friday that "the video lends further credence to Beijing`s claims, especially the oft-ignored assertions of links between domestic and foreign terrorist elements".

Rian Thum, a Uighur specialist at Loyola University New Orleans, said the Uighurs in the video were presented in the style of Islamic State propaganda.

"To me, the video says more about Islamic State tactics, propaganda, and ideology than it does about the relationship between Uighurs and the Chinese state," Thum said.
