Ukraine’s U.N. ambassador called Russia a “pariah state" after Moscow launched one of its heaviest overnight attacks on Kyiv, killing at least 18 people and wounding more than 90 people.

Iryna Moskaeva and her children jumped out of their beds and started running after an explosion rocked their Kyiv apartment early on Thursday, one of many residential buildings hit during a massive Russian attack that killed at least 27 people across the Ukrainian capital.
