BEIJING - Twenty tourists from South Africa, Britain and India were detained in China and some may face criminal charges after being accused of watching "propaganda videos", a charity said Wednesday.
Gift of the Givers, a disaster relief charity based in South Africa's Pietermaritzburg, said the 20 were held Friday at Ordos airport in China's Inner Mongolia region.
It said 10 were South Africans, nine British, and one an Indian national.
"No reasons were given for the arrest. The Chinese, now trying to find reasons for the detention suggested that some members were linked to a terror group," it added.
The group's founder Imtiaz Sooliman told AFP Wednesday that 11 of the detained - five South Africans and six Britons - had been released and would return home.
The nine others "are being held without charge at a detention centre on the accusation that they were watching propaganda videos," the group said on a Facebook page.
The families of the five South Africans still detained were "looking for an international human rights lawyer, but to help them with what?" Sooliman said. "They have no idea why they're being held." The public security ministry in Beijing did not immediately respond to a request for comment by AFP.
Chinese regulations passed in 2000 ban foreigners from all missionary activity including "distributing religious propaganda materials." The ruling Communist party, suspicious of overseas groups, has in recent months tightened controls on foreign charities working in the country.
State-run media have accused some groups of attempting to foment revolution and overthrow the party.
Police too have cracked down on foreign missionaries in China, detaining a Canadian Christian couple near the North Korean border last year.
Beijing also blames what it calls Islamist terrorists for ongoing violence in the mainly Muslim far western region of Xinjiang.
The South Africans were originally detained "with no access to communication or legal representation" and included several doctors, Gift of the Givers said.
The group's planned 47-day tour of China had gone "horribly wrong", it added.
A spokeswoman for the British embassy in Beijing said Wednesday that 11 British citizens had been held in northern China, two of whom held South African dual nationality.
Six would be deported "shortly", spokeswoman Natasha Simpson said, adding officials were seeking "further clarifications" on the detentions.
South African foreign affairs ministry spokesman Nelson Kgwete told local television that the government had been informed "about the arrest of 10 South African citizens in China" and the embassy was providing consular assistance.
