It’s been just over a month since the Ukrainian military launched an incursion into the Russian region of Kursk. It was a surprising move, and Ukrainian officials say it was a success. But it has meant a barrage of Russian attacks against Ukrainian cities, especially ones along the frontlines. The Globe’s Senior International Correspondent Mark MacKinnon has spent the last two weeks near the frontlines of the war – in Sumy, just across the border from Kursk, and in the battle-worn Donbas. He tells us what it’s like for residents of these regions and whether the incursion was worth the risk to the other frontlines of the war. Questions? Comments? Ideas? Email us at [email protected]
