Russia launched a massive attack on Ukraine's Kharkiv, killing four and injuring dozens. President Zelenskyy condemned the violence and appealed for urgent air defense assistance.

Russia has launched an intense missile and drone bombardment of Ukraine’s capital Kyiv in apparent retaliation for Ukraine's audacious drone strike on Russian military aircraft earlier this week.

The attack on Friday, which killed at least four people nationwide, came two days after Russia vowed retaliation for an audacious drone assault on its strategic bomber bases.
