KIEV, Jan. 30 – Blockages by activists and parliament lawmakers of railway lines used for transporting cargo to and from areas of occupied areas in Ukraine via several checkpoints may be construed as illegal acts, which incur losses to the state and create preconditions for the collapse of the nation's heat-generating system," Ukraine's SBU State Security Service warned.

According to the SBU statement released on Monday, the blockages may be prosecutable under Articles 278 of the Criminal Code of Ukraine (commandeering or seizing railways, aviation, naval or river transport infrastructure), Article 279 (blocking transportation lines, as well as seizing transportation enterprises) and Article 280 (preventing transportation workers from conducting their duties).
