Pressure is growing on the Venezuelan interim government to free the remaining political prisoners being held in the country.
A pressure group campaigning on detainees' behalf, Foro Penal, said on Sunday that it had been able to verify that 444 political prisoners had been released since US forces seized Venezuelan leader Nicolás Maduro last month.
But hundreds more remain behind bars, according to a tally kept by Foro Penal, even though the Trump administration has pressured Venezuelan officials to speed up their release.
Activists say the health of some relatives who have gone on hunger strike to demand the release of their loved ones is quickly deteriorating.
Opposition party Vente Venezuela posted footage of one of the relatives - who appears to be unconscious - being tended to by others outside the Zona 7 detention centre in the capital, Caracas.
