The US is to seek the extradition of three officials with a trading company in Co Sligo who have been charged with sending helicopter engines and other aircraft parts to Iran.
The 25-count indictment, which was opened today, charges Mac Aviation of Drumcliffe, Co Sligo and its officers of buying the components from US companies and sending them to Iran through other countries, including Malaysia.
A US Justice Department official said they were seeking the arrest of company owner Tom McGuinn, 72, his son Sean McGuinn, 40, who is the sales director, and commercial manager Sean Byrne.
The indictment says the men violated US sanctions banning the export of military technologies to Iran.
They claim the men violated the sanctions by 'deceit, craft, trickery and dishonest means'.
If convicted of the charges, the defendants face up to 20 years in prison.
