The Ukrainian Air Force says a "serious shortage" of interceptor missiles meant none of the 23 ballistic missiles fired by Russia at Kyiv on Sunday night were shot down, BBC reported.
At least 15 people were killed in the second large-scale Russian attack on the Ukrainian capital in a week, officials said. Eight more were killed in the wider Kyiv region.
Ukrainian President Volodymyr Zelensky has appealed for allies to take "strong decisions" at this week's Nato summit to provide Kyiv with air defences.
