Ukrainian miner Vasyl Yavorsky donated his own wages to striking Welsh miners in 1984. Now Welsh miners loaded up on medicine and supplies driven from south Wales to Kyiv to repay the old favour.
Not to say that back in 2014 clashes and provocations started* around Donetsk, one of the most notable mining regions not only in Ukraine, but in the whole ex-USSR, so the first victims to this war were probably miners as well.
* The first ones actually started way before in Kyiv, but these are the first that included in CTO, now war.
