Ukraine resumes attacks on Russian oil refineries, officials say, after brief truce

Ukraine has resumed its offensive against Russian oil refineries following a brief truce that was rejected by Moscow. The attack on a refinery in Russia's Ryazan region marks a significant escalation in the conflict, reflecting Ukraine's strategy to target energy infrastructure as a means to weaken Russia's war efforts. This move is especially noteworthy given the recent high-profile statements by President Volodymyr Zelenskyy, indicating a shift in tactics as the war continues to rage on. The resumption of these attacks could have broader implications for regional energy supplies and the economic pressures on Russia.
