The discussions on November 10 and 11 are intended to restart negotiations after more than four and a half years of conflict.
The strikes also hit several residential buildings, beyond energy sites and networks.
In Kyiv, at a kindergarten, staff sort through debris after the strikes.
Children's toys lie amid the rubble in the affected residential areas.
These attacks mainly target energy facilities, according to the Ukrainian forces' assessment.
The Ukrainian president thus places the barrage of ballistic missiles within Russia's preparations for trilateral talks.
According to the Ukrainian military, 36 ballistic missiles and 172 Russian drones targeted the country on the night of Friday, November 6, to Saturday, November 7. Volodymyr Zelensky said that"Russia is preparing for trilateral talks by launching ballistic missiles at Ukraine's critical infrastructure."According to the Ukrainian military, energy facilities and transport and distribution networks were particularly affected.
