Dozens of ethnic Uighurs, including several children, remain unaccounted for more than three months after China launched a crackdown on ethnic unrest in the country's far west, a human right group has said.

　　A report by Human Rights Watch (HRW) released on Wednesday, said the group had documented the cases of at least 43 Uighur men and boys who have disappeared in a wave of arrests across the city of Urumqi.

　　The group said the 43 cases were likely to be "just the tip of the iceberg", with the real number of disappeared in Urumqi and elsewhere in the Xinjiang region thought to be much higher.

　　'Disappeared' persons, it said, are often at high risk of torture or extrajudicial execution.

　　Chinese security forces launched a massive security crackdown in Xinjiang in early July, following riots in Urumqi by the region's indigenous Uighur minority.

　　In its report, entitled "We Are Afraid to Even Look for Them", HRW quoted Uighur residents in Urumqi describing how security forces raided several neighborhoods following the riots.

　　The witnesses told the group that in several cases police had hauled away male residents who either had wounds or were not at home during street protests.

　　Snatched

　　"They told everybody to get out of the houses. Women and elderly were told to stand aside, and all men, 12 to 45 years old, were lined up against the wall," a resident identified as Aysanam was quoted as saying.

　　Some men were pushed on their knees, with hands tied around wooden sticks behind their backs; others were forced on the ground with hands on their heads," she said.

　　In another incident, the report said soldiers had snatched a 14-year-old boy named Sharafutdin from the street. He has not been seen since.

　　HRW said the boy's father has asked at the local police station five times as to the whereabouts of his son, only to be told Sharafutdin was not on their list of detainees.

　　Commenting on the findings, Brad Adams, HRW's Asia director, called on the international community to press China for "clear answers about whathappened to those who have disappeared," saying trade issues and other concerns should not mean China is treated any differently.

　　'Dead or alive'

　　"The Chinese government says it respects the rule of law, but nothing could undermine this claim more than taking people from their homes or off the street and 'disappearing' them – leaving their families unsure whether they are dead or alive."

　　He added: "'Disappearing' people is not the behavior of countries aspiring to global leadership."

　　While condemning the reported disappearances, the HRW report also criticized Uighurs who had led attacks on members of the Han community during the unrest.

　　It said that while the July 5 demonstration was initially peaceful, the protest had later descended into an attack on Han Chinese in the city.

　　China has sentenced 12 people to death over the July violence, with hundreds more thought to remain in custody.
