Ireland's deputy prime minister Micheal Martin on Friday called Israel's "reprimand" of its ambassador "totally unacceptable", after Dublin announced moves to recognise a Palestinian state.
Ireland, Norway and Spain said on Wednesday that they will formally recognise statehood on May 28 and Israel immediately vowed counter-measures.
Irish ambassador Sonya McGuinness and her Norwegian and Spanish counterpart were summoned on Thursday. Israel's foreign ministry said it showed them a video of the kidnapping of five women soldiers during the October 7 attack by Hamas that set off the Gaza war.
Martin, who is also Ireland's foreign minister, told reporters: "I find that totally unacceptable and no way to treat diplomats, and is outside the norm by which diplomats are treated in any country."
Showing the ambassador the video in front of Israeli media was something they had not "witnessed before in other countries or jurisdictions", he added.
"Most people would accept internationally that that's not within the parameters of acceptable norms in terms of how people engage with diplomats," he said.
Israel's foreign minister Israel Katz said the video would be shown as part of a "severe demarche" or formal diplomatic protest.
Israeli officials have repeatedly criticised the three countries. Katz called their decision "a gold medal to Hamas terrorists who kidnapped our daughters and burend infants".
Irish Prime Minister Simon Harris said recognition was "a statement of unequivocal support for a two-state solution, the only credible path to peace and security for Israel, for Palestine and for their peoples."
The October 7 attack on Israel resulted in the deaths of more than 1,170 people, mostly civilians, according to an AFP tally based on Israeli official figures. Some 252 people were taken hostage.
Israel's retaliatory offensive against Hamas has killed at least 35,800 people in Gaza, also mostly civilians, according to the Hamas-run territory's health ministry.
