Ireland and Spain have requested an EU investigation into whether or not Israel is “complying with its obligations to respect human rights in Gaza,” Spanish Prime Minister Pedro Sanchez announced today.

According to CNN, Sanchez and Ireland’s Prime Minister Leo Varadkar wrote a letter to the President of the European Commission, asking the Commission to “undertake an urgent review of whether Israel is complying with its obligations, including under the EU/Israel Association Agreement, which makes respect for human rights and democratic principles an essential element of the relationship.”

The leaders told EU chief Ursula von der Leyen that they are “deeply concerned at the deteriorating situation in Israel and Gaza,” especially with the impact the conflict is having on “innocent Palestinians, especially children and women.”
