**Ukraine Fights Back as Russia's Invasion Hits Fourth Year** As Russia's invasion of Ukraine reaches a somber milestone, the war has taken a new turn on the battlefield. Despite Russia's aerial attacks, Ukraine has made significant gains in the south, pushing back the invaders and improving its air defences. This resilience has kept the lights on in Kyiv, even as the city faced two barrages of drones and missiles in the past week. Ukrainian President Volodymyr Zelenskyy has announced that his country has regained control of over 300 square kilometres of territory in the south, with some estimates suggesting the figure could be as high as 400 square kilometres. This is a significant development, considering the scale of the losses Ukraine has suffered over the past four years. Experts attribute Ukraine's successes to its determination and resourcefulness. By persuading Starlink to disconnect Russian military terminals, and by disabling the Telegram messaging service, Ukraine has disrupted Russia's communication networks. This has put Russia's plans for a spring offensive in jeopardy, according to the Institute for the Study of War. The war has been a brutal and costly one for Ukraine, with hundreds of thousands of lives lost and significant infrastructure destroyed. European leaders have noted that Russia's campaign has been flagging for a long time, with limited gains at a high cost. Even in areas where Russia has made progress, such as the city of Pokrovsk, the campaign has been marked by slow and painstaking gains. The battle for Kyiv has also been intense, with Russia launching a barrage of over 1,500 drones and missiles in the past week. However, Ukraine's air defences have held strong, downing most of the attacks and keeping critical infrastructure intact. President Zelenskyy has noted that Russia's aerial campaign is a sign of desperation, with the country's military unable to make a significant impact on the ground. As the war enters its fifth year, Ukraine's determination and resilience are a testament to its people's refusal to give up. Despite the challenges and losses, Ukraine remains committed to its cause, and its successes on the battlefield are a reminder that the war is far from over.
