Austria expels four Vienna-based Russian diplomats on security grounds

The Austrian Foreign Ministry announced on Friday the expulsion of four Russian diplomats based in Vienna. The officials were declared personae non gratae due to conduct described as "activities incompatible with their diplomatic status," a standard diplomatic designation typically associated with espionage allegations.

In response to the expulsion, the Russian government has formally vowed to retaliate against Austria. The incident marks a significant development in the ongoing diplomatic tensions between the two nations.
