Great Britain on August 6 requested that three Irish nationals detained in the west Slovak city of Piešťany last month be extradited to Britain to face charges.
British police have said the three are associated with the Real IRA, a terrorist group based in Northern Ireland which split from the mainstream IRA, and has been held responsible for several bombings.
The three men are being defended by Slovak lawyer Ján Gereg, who expressed anger that neither he nor his clients had been shown a text of the British extradition demand. "How can I defend them when I don't know what I am defending them against?" he asked.
Gereg has had a high-profile legal career, during which he defended Mikuláš Černák, a man Slovak police say was head of the Slovak underworld before his murder conviction last year.
