The University of Sydney has moved to sack controversial senior lecturer Tim Anderson after he showed students material featuring the Nazi swastika imposed over the flag of Israel.

Dr Anderson attracted criticism from federal education ministers for his numerous trips to Syria and North Korea, where he expressed solidarity with their dictatorial regimes and condemned Western imperialism and the United States.

He regularly posted on social media about the crimes of the "apartheid" Israeli state, and complained the mainstream media was complicit in distorting the narrative about Israel and Palestine.

A spokeswoman for the university confirmed Dr Anderson had been served a termination notice as he had engaged in "serious misconduct".
