British Labor Party head Jeremy Corbyn visited the former Nazi concentration camp Theresienstadt during his visit to the Czech Republic over the weekend.

Corbyn paid tribute to the victims of the camp at the site, which is now a memorial and museum, on Saturday.

He tweeted about his visit: “Yesterday, I visited Terezin Memorial – a World War II concentration camp and former Jewish ghetto. Never forget.”

Corbyn’s visit comes in the wake of a report by British lawmakers on the Home Affairs Select Committee, who accused him of doing too little to curb rampant anti-Semitism among party members and lawmakers, some of whom have been suspended for making racist and anti-Semitic statements on social media and in other public forums.

In October, a British parliamentary committee of inquiry upheld claims that the Labour party’s leadership was failing to confront seriously anti-Semitism in its ranks.

Raised persistently by leaders of British Jewry following the election last year of Corbyn to lead Labour, the accusation was reaffirmed in the publication of a scathing report entitled “Antisemitism in the UK” compiled by the Home Affairs Select Committee of the House of Commons, the lower house of the British Parliament.
