Aggression by Russia against Poland or another EU country is possible in the near future.

This is an assessment by Andrii Deshchytsia, the Ambassador of Ukraine in Poland, in an interview with "European Pravda" (read in Ukrainian).

"Russia is preparing to attack Poland. Diplomatic missions, including the Russian Embassy in Warsaw, probably have this information. And they are covering their tracks," said the Ukrainian ambassador.

Also there is a video confirmation from Russian state TV channels.

Ambassador referred to the smoke over the Russian embassy in Warsaw. A similar smoke over the Kyiv embassy of the Russian Federation was noticed on the eve of the invasion.

"It is clear why they are doing this. If there had been information and documentation that would not have caused Poland any harm, they would not even burn it, even if they had to leave the embassy. But if the documents or archives at the Embassy contain evidence of any subversive activities of Russian diplomats in Poland, this is a serious accusation and a serious argument that can be used later in an international criminal court against Russia," said Deshchytsia.

He believes that Russia is now trying to create a pretext for the use of weapons.

"Russia needed at least some excuse to invade Ukraine. But in order to enter Poland, which is a member of the EU and NATO, it is necessary to prepare much more seriously. Russia needs to have serious arguments as to why it intends to interfere in Poland's internal life and attack Poland," he said.

The destruction of the Russian embassy building could be such a reason. "Then, under this pretext, Russia would send spetznaz (special forces) to protect it. During such an operation, there is provocation, a Russian soldier is killed, and then Russia has a reason to send in its troops," Deshchytsia added.

He specified that the Polish government is currently trying to minimise this risk. "You know that the Polish government has decided to expel some 40 Russian diplomats who have been engaged in espionage and sabotage activities. And this confirms that Poland is doing everything possible to prevent the spread of war on its territory and stop possible provocation from Russian special services or so-called "diplomatic staff", he explains.
