The Taoiseach has accused the EU and some western countries of "double standards" by their rejection of Vladimir Putin's war in Ukraine, which he said is not matched in their response to Israel's actions in Gaza.
Speaking on RTÉ's The Week in Politics, Leo Varadkar said Ireland "went out on a bit of a limb" internationally by being one of the first countries calling for a ceasefire.
"From the very first few days after this phase of the conflict began, Ireland took a very clear position that Israel had a right to defend itself, but did not have the right to breach humanitarian law," Mr Varadkar said.
He said Ireland had been very active in terms of increasing humanitarian aid for Gaza.
Asked if the opposition had a point when they claimed there were double standards in the response to Ukraine compared to Gaza, he said: "I don't think that is true in relation to Ireland.
"If they are saying that in relation to the EU and some western powers. I think they are correct.
"I made that point at the peace conference in Paris, that there cannot be double standards when it comes to the conflict in Ukraine.
"And when it comes to international humanitarian law it has to be applied across the board.
"It is seen as double standards that the absolute rejection of what Putin has done in Ukraine is not being matched with a similar response in relation to Israel."
Mr Varadkar also said that Shannon Airport is not being used by the US military to supply weapons to Israel.
"You have to receive express permission to bring munitions through any airport in Ireland.
"They have to be signed off on by the Department of Transport and the Minister for Transport. That is not happening," he said.
He was speaking ahead of a Dáil debate on a people before Profit Solidarity motion, which states there are no inspections taking place of US military aircraft passing through the airport.
The Government has confirmed that 50 Irish citizens and their dependants have fled Gaza in recent days as part of international efforts to evacuate people with foreign passports.
Some Irish citizens from Gaza arrived from Cairo at Dublin Airport this weekend.
