Top UK Jewish officials have expressed concern over a Sunday Times report that Labour Party leader Jeremy Corbyn took part in an event at a Tunisian cemetery in 2014 during which a dead Palestinian terrorist linked to the 1972 Munich massacre was honored.

“It is high time that Jeremy Corbyn clarify his views regarding Palestinian terrorism,” Simon Johnson — CEO of the Jewish Leadership Council — was quoted by the Jewish Chronicle as saying. “At first sight, attending a wreath-laying ceremony of a known terrorist, who led one of the most notorious acts of international terrorism, the attack on the Munich Olympics, would appear to be beyond the pale.”

Jennifer Gerber — director of Labour Friends of Israel — was quoted as saying, “It is almost unbelievable that any Labour MP would participate in a ceremony honoring a man involved in the vicious murder of innocent Israeli athletes. Unfortunately, this appears to be part of a very disturbing pattern of behavior and we are seeking urgent clarification from the leader’s office on this matter.”

In an October 2014 column he wrote for the Morning Star newspaper, Corbyn recalled his recent participation in a “poignant” ceremony at which wreaths were laid on the graves of Palestinians “killed by Mossad agents in Paris in 1991.”

According to the Sunday Times, that was an “apparent reference” to Atef Bseiso, the Palestine Liberation Organization intelligence chief who was gunned down by unidentified assailants in the French capital in June 1992.

A Sunday Times reporter confirmed Bseiso was buried at the cemetery Corbyn visited.

According to the latest polls, Corbyn’s Labour Party is narrowing the gap with Prime Minister Theresa May’s Conservative Party ahead of the June 8 parliamentary elections in the UK.
