French presidential candidate Jean-Luc Melanchon:

If you're Ukrainian, you obviously can't accept your capital being bombed, so whatever you have at hand to protect yourself, use it. And you are legitimate to do so because you are the one being invaded.

But we, who are around you, also have something to say. Do you imagine that the Russians will accept that we are hitting Moscow and they will just sit there with their hands folded?

Do you know we shoot French and British weapons? you know that Therefore, we become warriors. This is the worst case scenario.
