Russia keeps attacking Ukrainian ports, and Ukrainian bulk carriers with grain and doesn't bother to explain these actions: It's a terror in the purest, clearest form.
And it was not the "Ukrainian-Russian conflict" that caused it, as some analysts put it. This notion is wrong due to the fact that Ukraine has never started any war, never in its history. It's the unprovoked and unjustified Russian aggression against Ukraine that has caused repercussions all around the globe.
