Four Palestinians, who were detained at Katunayaka Airport, face being deported to a Syria refugee camp, reported Al Jazeera.
The men, who fled refugee camps in Syria, have been in detention in a military prison for the past four weeks and were treated inhumanely according to a Palestinian rights organisation.
"They were directly taken to the military prison, where they described the treatment as inhuman," spokesman for the Palestinian League for Human Rights – Syria, Salim Salamah, told Al Jazeera.
"The Palestinian League for Human Rights - Syria calls for deporting them to a country where their rights will be respected and where they will not be subject to any threat."
“[UNHCR] needs to start considering including the Palestinians of Syria in their mandate... Also, we call on the EU countries to take into consideration the crisis of those four young men and to offer them a safe shelter," Salamah added.
Sri Lankan border officials did not respond to Al Jazeera's repeated requests for comment.
