Today (13th), the 18th day of Russia's invasion of Ukraine, Russian troops launched an airstrike in the area adjacent to the Polish border.



According to AFP and Reuters, the Russian army attacked a military training facility just 25 km from the Polish border early this morning local time.



Lviv regional military authorities said in a statement: "Occupiers have attacked the International Peace and Security Center, IPSC.



Anton Mironovich, spokesman for the Ukrainian Military Academy, said the attack was aimed at military installations and said that "there have been no reports of fatalities, but information about the wounded is not clear," Reuters said.



IPSC is a Ukrainian military training facility located in Yavoriu, 40 km northwest of the city of Lviv in western Ukraine.



It is only 25 km from the Polish border.



This is the first time that Russian forces have conducted air strikes in western Ukraine, which borders Poland, since the invasion.



According to NATO documents, the IPSC is a facility that trains Ukrainian and foreign troops in the safe clearing and handling of mines, and is where international troops are regularly stationed, the BBC said.



Foreign media noted that the attack took place near Lviv in western Ukraine.



So far, Russian forces have targeted the northern, eastern and southern regions of Ukraine as their main target of attack.



Recently, however, airstrikes have been carried out in western areas such as Ivano Frankiusk.



In particular, Lviv is a city located only 80 km from the Polish border and is the place where many Ukrainians have taken refuge.



The airport in the city of Ivano-Frankiusk in southwestern Ukraine was also targeted by the airstrikes.



Ivano-Frankiusk Mayor Roslan Marchinkiu said: "There was an explosion at the airport early this morning due to a Russian attack."



No casualties have been identified.



Meanwhile, NATO Secretary-General Jens Stoltenberg said Russia could use chemical weapons after the invasion of Ukraine.



"Recently, we have heard absurd claims about the biological and chemical weapons laboratory," Stoltenberg said in an interview with German newspaper Welt am Zontag today, according to Reuters and DPA news agency. Said it was being devised.



"Since these false claims have been made, we have the potential for Russia to launch its own chemical weapons operation for false manipulation," he said. "We must remain vigilant."



"It would be a war crime," he added.



Stoltenberg said the Ukrainian people are bravely resisting the Russian invasion, but the next few days are likely to bring more difficulties.
