He said this in an interview with TASS.
"As we understand it, these steps of the Ukrainian authorities were not coordinated with their Western masters," Galuzin said.
According to him, Western countries refrained from condemning this terrorist attack and preferred to remain silent.
The Russian diplomat also stressed that by its actions the Kyiv regime has demonstrated that no international legal, universal and moral norms "mean anything" to it.
Earlier, the press secretary of the President of Russia Dmitry Peskov said that it does not matter which of the units of Kiev attacked the Kremlin - the Kiev regime is behind this one way or another.
On the night of May 3, the Kyiv regime attempted to strike with unmanned aerial vehicles at the Kremlin residence of the president.
