NEW YORK, Jan. 20 (Xinhua) -- UN Secretary-General Antonio Guterres on Saturday warned against all forms of hatred at a ceremony marking the International Day of Commemoration in Memory of the Victims of the Holocaust.

In his remarks delivered at Park East Synagogue in New York, the UN chief said "as I scan the global landscape today, I am sorry to say that the state of our world is messy. And the state of hate is high."

"Neo-Nazi threat is growing," he noted.

"Almost 80 years after the fall of the Nazi regime, its symbols, mindsets and language are very much with us," said Guterres.

"Some still seek to deny or diminish the fact of the Holocaust. Others downplay the complicity of their citizens and former political leaders," he said.

"And we see example after example of the rise of the neo-Nazi threat," he warned.

Guterres said that "all of us today have a special obligation. An obligation to never lose sight of what went wrong and how it happened."

He also called upon the international community to "be ever vigilant in the face of persistent anti-Semitism and other forms of hate in our time."
