LVIV, Ukraine — Waves of Russian missiles pounded a military training base in western Ukraine on Sunday, killing 35 people in an attack on a facility that has served as a crucial hub for cooperation between Ukraine and the NATO countries supporting it in its defense against Moscow’s grinding assault.
More than 30 Russian cruise missiles targeted the sprawling facility, which lies not far from the border with NATO member Poland and that has long been used to train Ukrainian military personnel, often with instructors from the U.S. and other countries in the western alliance.
