The failed attack in Germany is one of several worrying incidents reported across Europe. Recent ones include a fire this week at a major drone-making factory in Poland. Russia is suspected in many cases. There have also been drone incursions in Estonia and Latvia resulting from Russia’s war in Ukraine.

The move comes after Berlin blamed Moscow for an attempted attack at Leipzig/Halle Airport last month and announced the closure of both the Russian Consulate in Bonn and the Russian House cultural center in the German capital.
