The Iranian-backed Lebanese Shiite movement Hezbollah denied allegations by some Bahraini parliamentarians that it was linked to a suspected terrorist cell recently arrested in the Gulf state, dpa reported.
Last week, Bahrain's interior ministry said the five-man group was planning to attack the ministry, the Saudi embassy in Manama and the bridge which links the state to Saudi Arabia.
Hezbollah described the claims as "ridiculous."
"No one knows if the individuals arrested by the Bahraini authorities were members of a military cell or if the cell had military objectives as claimed, and the whole thing could might be one of the fabrications of the authoritarian al-Khalifa regime," Lebanese radio quoted a Hezbollah statement as saying.
The suspects - all Bahrainis - were Sunday jailed for 60 days for questioning.
The Sunni-ruled Bahrain have repeatedly accused mainly Shiite Iran of meddling and inciting the Shiite-led protests which rocked Bahrain for a month in mid-February.
The Bahraini government have cracked down on pro-democracy protests with the help of Gulf Cooperation Council (GCC) troops, a move which has drawn condemnation from Tehran.
