Police in northeastern China said they fatally shot three minority Muslim Uighurs, calling them terrorists who were using knives to resist arrest.

Police also injured a fourth suspect during the incident Monday in Shenyang, the city police said in a statement on their microblog.

A man who refused to identify himself at Shenyang police's criminal offenses office said Tuesday that the four were ethnic Uighurs.

Uighurs (pronounced WEE-gurs) are a Muslim minority in China's far western region of Xinjiang. Beijing has accused Uighur separatists of terrorism in Xinjiang and elsewhere in China, including a knife attack at a train station in southwest Kunming city last year that killed 31 people.

Uighurs have complained of harsh cultural and religious suppression as well as economic marginalization in Xinjiang, where ethnic violence has left hundreds of people dead.

The police statement said no civilians were injured or killed during Monday's incident, and that investigations were continuing. It gave no other details.
