Kuwait had charged 25 of its nationals - all of them Shi'ites - and an Iranian citizen after the discovery of guns and explosives in a raid on the so-called "Abdali cell" in 2015, which escalated sectarian tensions.
Kuwait's Interior Ministry says 12 men with links to a terrorist group associated with Hezbollah and Iran's Revolutionary Guard have been arrested.
The suspects were arrested after a weeks-long manhunt, announced the Interior Ministry according to the Kuwait News Agency (KUNA). They had been on the run since their sentencing last month, and were seized in different parts across the Gulf state.
The Supreme Court in June overturned an acquittal by an appeals court and convicted 21 of forming a "terrorist cell" with ties to Iran and Hezbollah.
Kuwait has protested to Lebanon over the alleged training of the so-called "Abdali Cell" by Hezbollah, which has ministers in the Beirut government.
Last month, Kuwait asked Iran to reduce the number of Iranian diplomats in its embassy and closed down the Iranian cultural mission in the country.
Iran said the allegation is baseless.
