In a continued show of aggression, Russia unleashed a barrage of missiles and drone attacks on Ukraine, killing at least 6 people, according to live updates from The New York Times. Ukraine’s military reported that Russia fired 81 missiles and 8 drones in the morning strikes, marking a deadly increase in violence in the ongoing conflict between the two nations.

The strikes came after top U.S. spies warned that Russia is boosting its nuclear capabilities, as reported by CNBC. Moscow has been accused of waging a war in Ukraine for years, and tensions have been escalating as the Kremlin continues to flex its military might.

The Moscow Times reports that the strikes hit several areas in both the Donetsk and Luhansk regions of Ukraine. The deadly attacks have prompted condemnation from leaders around the world, with calls for an end to the violence and a diplomatic resolution to the conflict.

As the situation continues to escalate, live updates from CNN indicate ongoing clashes along the border between Russia and Ukraine, with Russian-backed separatists continuing to fight Ukrainian forces. The two nations have been locked in conflict since 2014, after Russia annexed Crimea from Ukraine.

Despite international condemnation and calls for peace, the conflict shows no signs of abating. As the world watches the situation closely, hopes remain that a peaceful resolution can be reached before more lives are lost.
