Iranian Foreign Minister Mohammad Javad Zarif today canceled a visit to Vienna, where nuclear negotiations are taking place, in protest at Chancellor Sebastian Kurz's decision to have the Israeli flag hoisted over the Chancellery.
This was reported on its website by the Reuters agency.
The Islamic Republic has a hostile position to Israel and supports Palestinian groups such as Hamas, which is currently engaged in conflict with the Jewish state.
Kurz called the decision to have the Israeli flag raised as an "act of solidarity" and condemned what he called "the terrorist attack on Israel".
Zarif was to meet the Austrian Foreign Minister Alexander Schallenberg in Vienna.
The news of the cancellation was confirmed by the spokesman of the same head of Austrian diplomacy.
The dispute takes place while negotiations are underway in Vienna for the re-entry of the US in the 2015 agreement on Iranian nuclear activities, an agreement from which Washington left in 2018 by decision of the then President Donald Trump.
