A brother of one of the men blamed for the Omagh bomb atrocity has been jailed for 12 years for trying to buy weapons and explosives in Lithuania.
Irishman Michael Campbell was arrested in an undercover operation in the Baltic state of Lithuania after handing over cash to buy a sniper rifle, detonators and timers for the Real IRA. The 39-year-old was convicted by Judge Arunas Kisielus after a two-year trial in the city of Vilnius.
He was arrested in January 2008 following the operation involving the Irish, British and Lithuanian intelligence agencies, which believe the explosives would have been used to mount a terror campaign in Northern Ireland and on the British mainland.
Prosecutors are still seeking the extradition of his brother Liam Campbell and Brendan McGuigan from Ireland.
Liam Campbell is seeking to go before the Supreme Court in London to challenge a civil court ruling which held him liable for the 1998 Omagh bomb, which killed 29 people including a woman pregnant with twins.
Campbell was arrested after a six-year sting orchestrated by MI5.
Video and intercepted communications showed he paid 6,000 euros for high-grade explosives, grenade launchers, detonators, AK-47s and a special assassin's rifle, to Lithuanian agents posing as arms dealers. He was charged with supporting the splinter group by attempting to smuggle firearms, ammunition, and explosive devices from Lithuania to Ireland.
Campbell - from the Upper Faughart area near Dundalk, Co Louth - maintained his innocence and claimed he was the victim of entrapment.
Irmantas Mikelionis, chief prosecutor of the Organised Crime and Corruption Investigations Department of the Prosecutor General's Office, said the explosives could have been used for bombing in London. "If we failed to stop Mr Campbell, we would put in danger the lives of innocent people," he said.
Secretary of State for Northern Ireland, Owen Paterson, said Campbell's conviction was another example of what can come from the high levels of co-operation between countries over terrorism. "I have no doubt that this will have dealt a blow to RIRA but we are not complacent and we remain determined to do all that we can to bear down on those who are the enemies of the whole community throughout the United Kingdom."
