Russia asks China for military help in war with Ukraine, U.S. officials say

Russia has asked China for support in its war against Ukraine, according to two U.S. officials. The request included military aid and equipment, but it's not clear what specifically Moscow has requested. 

Almost three weeks into its invasion into Ukraine, Russia has fallen far short of the progress Russian leaders anticipated, according to defense and intelligence officials. CIA Director William Burns told Congress last week that Russian President Vladimir Putin had counted on "seizing Kyiv within the first two days of the campaign." 

U.S. officials say that Russia's casualties range from 5,000 to 9,000 killed in action.
