Crowds pack Kyiv's railway station at 2am as thousands of people, many foreigners, try to leave the Ukrainian capital on Sunday, as the country puts up stiff resistance to Russia's invasion. Ukraine's army said it had held back an assault on the capital -- but was fighting Russian "sabotage groups" that had infiltrated the city. Occasional blasts of what soldiers said were artillery and Grad missiles being fired and loud explosions were heard in the city. IMAGES
