Spanish Prime Minister Pedro Sánchez told his nation in a televised address from Madrid that "this is a historic decision that has a single goal, and that is to help Israelis and Palestinians achieve peace."

Israel’s Foreign Minister Israel Katz quickly lashed out at Spain on X, saying Sánchez's government was "being complicit in inciting genocide against Jews and war crimes.”

Ireland and Norway soon joined Spain in formalizing a decision they had jointly announced the previous week.

The Palestinian flag was raised in Dublin outside Leinster House, the seat of the Irish parliament.

"This is an important moment and I think it sends a signal to the world that there are practical actions you can take as a country to help keep the hope and destination of a two-state solution alive at a time when others are trying to sadly bomb it into oblivion,” Irish Prime Minister Simon Harris said before his Cabinet meets to formally sign off on the decision.

Norwegian Foreign Minister Espen Barth Eide said in a statement that "for more than 30 years, Norway has been one of the strongest advocates for a Palestinian state. Today, when Norway officially recognizes Palestine as a state, is a milestone in the relationship between Norway and Palestine.”

While some 140 countries have recognized a Palestinian state - more than two-thirds of the United Nations - none of the major Western powers has done so. Still, the adherence of three European countries to the group represents a victory for Palestinian efforts in the world of public opinion, and will likely put pressure on EU heavyweights France and Germany to rethink their position.

Relations between the EU and Israel have nosedived with the diplomatic recognitions by two EU members, and Madrid insisting on Monday that the EU should take measures against Israel for its continued deadly attacks in southern Gaza’s city of Rafah.
