One of the EU’s highest-ranking officials on Thursday declared the war in Gaza a “genocide,” escalating criticism of Israel and condemning the bloc’s failure to intervene.

"The genocide in Gaza exposes Europe's failure to act and speak with one voice," European Commission vice president Teresa Ribera said during a speech in Paris.

Top EU officials have so far shied away from calling Israel's actions in the territory a "genocide." One spokesman said it was for the courts to make a legal judgment on whether genocide was happening.

The EU has struggled to take steps over the war in Gaza due to deep divisions between member states pushing for action against Israel and those backing the country.

The splits are also present inside the EU's executive, where Spanish commissioner Ribera has expressed frustration over the failure to push on the issue.
