The latest Russian missile barrage against Ukraine’s civilian infrastructure has marked one of the largest such attacks in months. 

On Thursday, Russia fired more than 80 missiles in a massive effort to overwhelm Ukrainian air defenses and cripple the country’s energy system. 

Russia has been regularly launching similar strikes since October in a bid to demoralize Ukrainians and force the government to bow to the Kremlin’s demands. 

Thursday’s strikes differed from earlier attacks, though, by including a larger number of sophisticated hypersonic missiles that are the most advanced weapons in the Russian arsenal. But just like previous barrages it has failed to cause lasting damage to the country’s energy network, with repair crews quickly restoring power supplies to most regions.
