Two asylum seekers have sewn their lips together and started a hunger strike in Greenock Prison.
The men, a Russian and a Palestinian, were transferred to the jail from the Dungavel detention centre.
BBC News OnlineThe Scottish Socialist Party called on the Scottish Executive to make a statement on the use of Greenock Prison to hold asylum seekers.
SSP justice spokesman Colin Fox said Justice Minister Cathy Jamieson should address the Scottish Parliament as "a matter of urgency".
He said: "The use of Scottish jails to hold asylum seekers who have committed no offence and who have not been charged with any crime is an extremely serious development.
"The executive can no longer remain silent when its ministers are now directly involved in the way that asylum seekers are being treated in Scotland."
