In a post marking the commemoration of Oct. 7, U.S. Secretary of State Marco Rubio said, “We will never forget this act of barbarism.”

Rubio is in Athens, Greece, for the dedication of the U.S. Embassy in Greece, which was recently renovated. While there, he posted an Oct. 7 message on X.

“Three years ago today, Hamas terrorists tortured, mutilated, and murdered 1,200 innocent civilians in Israel,” the secretary of state wrote.

“Among those slain were men, women, and children — including dozens of Americans,” he added.

“We will never forget this act of barbarism against an ally and recommit ourselves to the defense of civilization,” he declared.

World leaders also commemorated the day that Hamas invaded Israel and massacred 1,200 Israelis in the most brutal ways imaginable and took 251 hostages, touching off a long, grinding war in which Israel has sharply reduced the threat from Hamas by decimating its leadership and destroying its military capabilities.

German Chancellor Friedrich Mertz said that antisemitism was rising to historically high levels and that his government would do everything in its power to combat it while reaffirming his commitment to the two-state solution.

“Germany stands firmly by Israel’s side. Our Israeli friends can count on our commitment to ensuring that such a crime never happens again,” he said.

“We do not forget the names or the faces: those of Maya, Ohad, Valentin, and so many others,” said French President Emmanuel Macron. “Combating antisemitism and terrorism, everywhere and always, working for peace and the security of all: that is France’s commitment.”

British Prime Minister Andy Burnham posted a lengthy statement on X commemorating Oct. 7, acknowledging the rise in antisemitism in the United Kingdom, and vowing to fight it, though he did not address criticism that his anti-Israel policies were contributing to the rising hostility toward Jews.

“Three years on from the October 7 attacks on Israel, we remember those who were senselessly killed by Hamas terrorists,” the premier wrote. “The impact of the attacks has been felt not just in Israel, but in Jewish communities across the world who still bear the burden of the tragic events that day.”

“In the years since, we have seen a disturbing rise in antisemitic behaviour in the UK,” he added. “A year ago we witnessed a horrifying terrorist attack on the Heaton Park Hebrew Congregation in Manchester, with further attacks against Jewish people and institutions since.”

Burnham said he stands with the Jewish community and pledged his aid to fight antisemitism.

“I want Britain’s Jewish community to hear this from me directly. We stand with you. Abuse and violence against you, in any form, will not be tolerated. Not on our streets, not online, not in our schools or universities,” he wrote. “That’s why we are funding protection for synagogues, schools and community buildings, and why we will come down hard on antisemitism wherever it is found – in classrooms, on campuses and in neighbourhoods.”

“At home, we are committed to protecting our citizens from vile hatred. Abroad, we continue to work towards a two-state solution, with Israelis and Palestinians living side by side in peace and security,” he continued.

“An attack on Jewish people in Britain is an attack on all of us. Antisemitism has no place in this country, and we will do everything we can to stamp it out,” he concluded.
