![Ukraine Intensifies Guerrilla Tactics, Targeting Trains](https://cdn.shortpixel.ai/stsp/to_webp,q_lossy,ret_img/https://static01.nyt.com/images/2023/12/26/multimedia/00ukraine-sabotage-swap-gcqt/00ukraine-sabotage-swap-gcqt-facebookJumbo.jpg)
The saboteurs managed to place four explosives on a Russian freight train carrying diesel and jet fuel, roughly 3,000 miles from the Ukrainian border. But more important than the destruction of the train, Ukrainian intelligence officials said, was the timing of the blast.
They needed it to blow up as the 50 rail cars were traveling through the nine-mile-long tunnel through the Severomuysky mountains, the longest train tunnel in Russia.
The Ukrainians were hoping to compromise a vital conduit for weapons being shipped to Russia from North Korea, at a moment when Ukrainian forces on the front are struggling to stave off relentless Russian assaults. Trains can be replaced and tracks quickly repaired. But serious damage to this tunnel, which took decades to build, might not be so easy to fix.
Russia and Ukraine continue to battle on a large scale, both on the ground and with aerial strikes. Russian officials accused Ukraine of attacking a Russian city, Belgorod, on Saturday, killing at least 20 people and injuring more than 100 others, in apparent response to a huge Russian missile barrage on several Ukrainian cities the day before.
