Polish Prime Minister Mateusz Morawiecki is concerned about Germany's reaction to the escalation of the situation around Ukraine after reports that Germany is blocking NATO ally Estonia in providing military support to Ukraine, Reuters reported.

The Wall Street Journal reported that Berlin is refusing to issue permits for the export of German weapons to Ukraine.

“I observe with concern the situation in Ukraine and the reactions of our neighbors from Germany in the face of the threat from Russia,” Mateusz Morawiecki wrote in a Facebook post. “A great disappointment is, among other things, Germany withholding its consent for the supply of weapons from Estonia to a state that is preparing to defend itself against an aggressor.”

The German daily newspaper Bild quoted Latvian Defense Minister Artis Pabriks as calling Berlin's arms export policy for Ukraine a big mistake.

German Chancellor Olaf Scholz said his country has not supported arms exports in recent years.

Morawiecki said the black scenario that Poland had warned about was now being implemented, and the construction of Nord Stream 2 and Russia's gas blackmail gave Putin tools for terror in other European countries.
