Russian invasion runs into stiff resistance, supply lines are a 'definite vulnerability,' US officials say

Russia's invasion of Ukraine is encountering "stiffer than expected" resistance from the Ukrainian military as well as unexpected difficulties supplying its forces, two senior US officials with direct knowledge tell CNN.
On the battlefield, Russia is suffering heavier losses in personnel and armor and aircraft than expected. This is due in part to the fact that Ukrainian air defenses have performed better than pre-invasion US intelligence assessments had anticipated. In addition, Russia has yet to establish air supremacy over Ukraine, a senior dedfense official said, as the Ukrainian Air Force and air defense systems fight for control of the airspace.
"Ukrainian air defenses, including aircraft, do continue to be operable and continue to engage and deny access to Russian aircraft in places over the country," the official said.
