In a recent escalation of tensions between Israel and Poland, Warsaw canceled a scheduled state visit of an Israeli delegation, citing concerns that talks would focus on the restitution of Jewish properties from World War Two. CGTN's Aljosa Milenkovic tells us more from the Polish capital.

These are the faces of evil - rare photos of SS commanders and their troops in one of the worst Nazi concentration camps during the Second World War. Here in Treblinka, almost 900-thousand people - mostly Jews - were gassed to death by exhaust fumes from diesel engines.

ALJOSA MILENKOVIC TREBLINKA EXTERMINATION CAMP "This is where a mock train station used to be. Every day, between 10 and 20,000 people were brought in from across Europe only to be put to death. It was part of Adolf Hitler's so-called 'final solution'. Yet, many Jews see Treblinka as a sacred place."

That mass killing is known as the Holocaust. Over seven decades later, spirits still linger. A couple of years ago, the Israeli government accused Polish authorities for allegedly rewriting the Holocaust's history, with Warsaw denying any involvement in it and placing blame solely on the German Nazis. Tensions have escalated since then. The latest issue has been the restitution of seized Jewish property during the War – a debate that has dragged on for decades.

MONIKA KRAWCZYK HEAD, UNION OF JEWISH RELIGIOUS COMMUNITIES IN POLAND "Many of them had unsuccessfully claimed some of their properties, left during the war in Poland, and those claims are not resolved until today and they've started their effort in 1989."

Now, the issue has gained worldwide attention. When the United States stood behind Jewish restitution requests, Polish right-wing groups reacted with massive protests.

TOMASZ KALINOWSKI SPOKESMAN, NATIONAL RADICAL CAMP "This property is heirless, and the state took control of it. Today, the Jewish community wants to go around this. They want to get the money for themselves. For us, it's incomprehensible. It's an attempt to steal and rob Poland of 300 billion US dollars."

And while accusations are being traded back and forth, the Jewish community in Poland – a population of under 10,000 - says they feel a rise in anti-Semitism, mostly in the form of hate speech.

MICHAEL SCHUDRICH CHIEF RABBI OF POLAND "Nothing is really impact directly on Jews of Poland. But rather, we're upset that these friction between our government here and the government in Israel, between our government here and the government of the Unites States. So, it is more on a global level, we're upset that there is frictions where there shouldn't be, but it's not that we are afraid to walk outside."

And while all sides say they want to bury the hatchet, none seem to believe that the restitution issue will be resolved any time soon.
