Two Afghan Christian asylum seekers who fear death if they are returned home, were due to be deported to Kabulon on 27 April.
News is still awaited on the outcome of attempts to prevent the latest action of the UK government in removing people fleeing oppression and persecution.
One of the pair, Ahmed Faizi, aged 29, has been on a hunger strike at the Harmondsworth immigration removal centre near Heathrow during Holy Week.
Mr Faizi, who has a cross tattooed on his right arm, told a friend: "If the Taliban don't execute me for being a Christian, my family will."
He is fearful that the recent burning of a Qu'ran in the US would make Afghanistan even more hostile to Christian converts, reports the Guardian newspaper.
Fellow deportee Ali Hussani has expressed similar fears. "They will kill me for being Christian," he said. "There are only Muslims there."
A spokesman for the UK Board Agency declined to comment on the deportation, saying it was policy not to do so until the flight in question had landed - that is, until the deportation has taken place.
Campaigners have said they are "disgusted" by the "inhuman" attitudes and responses promoted by current policies on asylum, the pressure on officials to deport, and the failure of the authorities and tribunals to consider evidence thoroughly and properly.
