Explosions reportedly caused by Russian missiles killed two people in Poland, prompting the NATO member to consider an appeal for assistance from its allies in the alliance.
Polish authorities are investigating the blasts that happened about 4 miles from the frontier with Ukraine. The government in Warsaw may invoke NATO's Article 4, which allows allies to raise discussions on national security threats, a spokesman said.
“The authorities are on the spot and investigating the case and will continue to investigate it throughout the night or as long as necessary to clarify this case,” government spokesman Piotr Muller told reporters Tuesday. “We’ve also just decided to verify whether there are reasons to invoke procedures resulting from Article 4.”
