The organizations said they are also calling on the UNHCR to "take a position condemning the Tunisian government and its lies", referring to the fact that Tunisian authorities had denied that a deportation of migrants across the border to Libya had taken place.
"Just yesterday, the authorities were propagating fake news, saying that the deportation had never taken place, faulting Italian activists for releasing the video," the statement said.
"The people who were deported are still in the border area with Libya, and only with the presence of activists, various forms of pressure, and media attention have they thus far avoided the worst consequences."
'People must be immediately brought back to Sfax'
The organizations, namely LasciateCIEntrare, Meltingpot Europa, and Progetto20k-Carovane Migranti, said a UNHCR official they spoke with "confirmed she was aware of the deportation, but thus far the UN agency hasn't formally expressed an opinion, since this is not a question of asylum seekers. However, when asked whether there was a possibility to exercise the right to asylum at the border, she did not respond. Activists are calling for the people to be immediately brought back to Sfax, protected and left free to choose where they want to live!"
Tunisian authorities have not issued any official statements on the situation.
