Taoiseach Simon Harris has said he is seeking information on reports that Israeli-operated aircraft carrying weaponry from the United States to Israel flew through Irish airspace.
Speaking in Government Buildings, he said there are very clear consent protocols that would need to be followed for that to happen.
He said his understanding from the Department of Defence and the Department of Transport is no such consent was sought and he was expecting to hear an update from the relevant Government departments.
Reports of Israel-bound aircraft carrying munitions were published recently by The Ditch news website.
In a statement, the Department of Foreign Affairs said it is aware of media reports this week regarding civil aircraft flights to Israel.
It said that all foreign military aircraft wishing to overfly or land in Irish sovereign territory or airspace are required to obtain diplomatic clearance.
"Such clearance is subject to strict conditions, including that the aircraft is unarmed; that it carries no arms, ammunition or explosives; that it does not engage in intelligence gathering; and that the flight in question does not form part of a military exercise or operation.
"This diplomatic clearance procedure is fully compatible with Ireland's policy of military neutrality."
The department said that no applications have been received or exemptions granted in 2023 or 2024 for the carriage of munitions of war on civil aircraft to Israel.
People Before Profit TD Bríd Smith demanded answers about any use of Irish airspace to transport weapons.
"On 11 April 2024, the Tánaiste told me in the Dáil at Leaders' Questions that no airport in Ireland or Irish sovereign airspace is being used to transport weapons to the conflict in the Middle East," she said.
The People Before Profit TD has written to Tánaiste Micheál Martin asking him to now correct the Dáil record and to make a statement on the matter.
