Damage to the Druzhba pipeline has halted oil deliveries from Russia to Hungary, complicating a billion-dollar loan to Ukraine. Ukrainian officials attribute the damage to a Russian strike, while Hungary accuses Ukraine of sabotage. The European Commission has proposed an investigation. Hungary remains heavily reliant on Russian oil, with experts suggesting it has ignored warnings to diversify its energy sources. The Adria pipeline is cited as an alternative, but Hungary disputes its capacity. Analysts argue Hungary's dependence on Russian crude is driven by commercial interests rather than technical constraints.
