China has said reports it is holding a million Muslim Uighurs in detention in Xinjiang are "completely untrue".

Uighurs enjoyed full rights but "those deceived by religious extremism... shall be assisted by resettlement and re-education", officials said.

The rare admission from Beijing - at a UN meeting in Geneva - came in response to concerns that the region "resembles a massive internment camp".

Xinjiang has seen intermittent violence - followed by crackdowns - for years.

China accuses Islamist militants and separatists of orchestrating the trouble.

China has sent a 50-strong delegation to the two-day meeting of the UN Committee on the Elimination of Racial Discrimination.

On Friday, committee member Gay McDougall said she was concerned by reports that Beijing had "turned the Uighur autonomous region into something that resembles a massive internment camp".

In his response, Hu Lianhe, deputy director of China's United Front Work Department of the Communist Party Central Committee, said: "Xinjiang citizens, including the Uighurs, enjoy equal freedom and rights."

"The argument that one million Uighurs are detained in re-education centres is completely untrue," he added, before admitting the existence of resettlement or re-education programmes.

Correspondents say it is unusual for China to give public explanations about how it deals with the situation in Xinjiang.

Meanwhile the state-run English-language Global Times newspaper defended tough security measures in the region, which it said had prevented it from turning into "China's Syria" or "China's Libya".

"The turnaround in Xinjiang's security situation has avoided a great tragedy and saved countless lives," it said in an editorial.

However, Ms McDougall sought further clarification.

"You said I was false on the million, well, how many were there? Please tell me. And what were the laws on which they were detained?"
