Poland's statements about "Russian missiles" are a deliberate provocation to try and escalate the situation, the Russian Defense Ministry said on Tuesday.

According to Moscow's Defense Ministry, no strikes were carried out by Russian means near the Ukrainian-Polish border.

"Statements by the Polish media and officials about the alleged fall of 'Russian' missiles in the area of the settlement of Przewodow is a deliberate provocation in order to escalate the situation. No strikes were made against targets near the Ukrainian-Polish state border by Russian weapons," the ministry said.

They added that "the fragments published in hot pursuit by the Polish media from the scene in the village of Przewodow have nothing to do with Russian weapons."

In the wake of the unconfirmed reports, Ukraine called for NATO members to convene an "immediate" summit to bring tough measures against Moscow.

"A collective response to Russian actions must be tough and principled. Among immediate actions: a NATO summit with Ukraine's participation to craft further joint actions, which will force Russia to change its course on escalation, providing Ukraine with modern aircraft," Foreign Minister Dmytro Kuleba said in a statement on Twitter.

...which will force Russia to change its course on escalation, providing Ukraine with modern aircraft such as F-15 and F-16, as well as air defense systems, so that we can intercept any Russian missiles. Today, protecting Ukraine’s skies means protecting NATO 2/2

The Pentagon said it was unable to verify reports that 2 Russian missiles hit Poland soils, but it is investigating the claims. 

Amid reports about 2 missiles that fell in the village of Przewodów in the Lubelskie Voivodeship near the border with Ukraine, Warsaw called for an emergency national security council meeting.

"We are aware of the press reports alleging that two Russian missiles have struck a location inside Poland or the Ukraine border," said Pentagon spokesman Pat Ryder.

"We have no information right now to corroborate that there has been a missile strike," Ryder told reporters, adding that the Pentagon was "looking into this further."

Russia increases shelling of Ukraine power infrastructure

Russia shelled several Ukrainian infrastructure sites today following its withdrawal from Kherson and amid signs that Moscow's retreating forces were going further back from the southern Dnieper River.

Air raid sirens were heard blaring throughout Ukraine in nearly a dozen major cities after a massive barrage of missiles as Moscow tries to regain ground amid retreats in the east.

Strikes and explosions were reported in the cities of Kiev, Lvov, and Zhitomir in the west, Krivoy Rog in the south, and Kharkov in the east. According to regional officials in Ukraine, some of the attacks caused a power outage after hitting electricity supplies.

According to Kyrylo Tymoshenko, deputy head of Volodymyr Zelenskyy's office, Tuesday saw the launch of more than 90 missiles at Ukraine, damaging 15 energy infrastructure facilities across the country. He reported the damage in a commentary to local TV channels.
