KYIV – Russian missiles struck Ukraines eastern city of Kharkiv, the capital Kyiv and western Lviv on Thursday, causing a series of explosions, mayors said.
Kharkivs Ihor Terekhov said officials were clarifying what had been hit and whether there were any casualties.
Kyivs Vitali Klitschko warned of possible power cuts there and asked residents to charge their phones.
Two private houses in Darnytskyi district were damaged by the fragments of downed missiles, the Kyiv city military administration said on Telegram.
It said a business and a playground were also damaged and the situation of the victims is being clarified.
Lvivs mayor Andriy Sadovyi said on Telegram that 90 per cent of the city was without electricity and electric public transport was not running.
There may be interruptions in water supply, he added.
Earlier, presidential office adviser Oleksiy Arestovych wrote on Facebook that more than 100 missiles were incoming in several waves, and air raid alarms could be heard across the country.
Blasts were heard in Kyiv, Zhytomyr and Odesa, according to a Reuters correspondent and local media reports.
Power cuts were announced in the Odesa and Dnipropetrovsk regions, aimed at minimising potential damage to the energy infrastructure.
The blitz came hard on the heels of the Kremlins rejection of a Ukrainian peace plan, insisting that Kyiv accept Russias annexation of four regions.
Moscow has repeatedly denied targeting civilians.
But Ukraine says its daily bombardment is destroying cities, towns, and the countrys infrastructrure from power to medical.
On Wednesday, Russian shelling hit the maternity wing of a hospital in the city of Kherson, though no one was hurt, according to Mr Kyrylo Tymoshenko, President Volodymyr Zelenskys deputy chief of staff.
Staff and patients were moved to a shelter, Mr Tymoshenko said in a post on Telegram.
It was frightening … the explosions began abruptly, the window handle started to tear off … oh, my hands are still shaking, Ms Olha Prysidko, a new mother, said.
When we came to the basement, the shelling wasnt over. Not for a minute.
Ukraines recently liberated southern city of Kherson has remained under constant bombardment from Russian forces.
They retreated to the east bank of the river when the city was retaken in a major victory for Ukraine last month.
Mr Zelensky, in a video address, urged Ukrainians to hug loved ones, tell friends they appreciate them, support colleagues, thank their parents and rejoice with their children more often.
We have not lost our humanity, although we have endured terrible months, he said. And we will not lose it, although there is a difficult year ahead.

There is still no prospect of talks to end the war.
Mr Zelensky is vigorously pushing a 10-point peace plan that envisages Russia respecting Ukraines territorial integrity and pulling out all its troops.
But Moscow dismissed it on Wednesday, reiterating Kyiv must accept Russias annexation of the four regions Luhansk and Donetsk in the east, and Kherson and Zaporizhzhia in the south.
There can be no peace plan that does not take into account todays realities regarding Russian territory, with the entry of four regions into Russia, Kremlin spokesman Dmitry Peskov said.
Russian Foreign Minister Sergey Lavrov said Mr Zelenskys idea of driving Russia out of eastern Ukraine and Crimea with Western help and getting Moscow to pay damages to Kyiv is an illusion, the RIA news agency reported.

Mr Zelensky told Parliament to remain united and praised Ukrainians for helping the West find itself again.
Our national colours are today an international symbol of courage and indomitability of the whole world, he said in an annual speech held behind closed doors. Kherson attacks
On the battlefront, Russia shelled more than 25 settlements around Kherson and Zaporizhzhia, the General Staff of Ukraines Armed Forces said on Wednesday. The Kherson region, at the mouth of the Dnipro, serves as a gateway to Russian-annexed Crimea.
Heavy fighting persisted around the Ukrainian-held city of Bakhmut, in the eastern province of Donetsk, and to its north, around the cities of Svatove and Kreminna in Luhansk, where Ukrainian forces are trying to break Russian defensive lines.
Britains Defence Ministry said Russia has likely reinforced the Kreminna section of the frontline, as it is logistically important and relatively vulnerable following Ukrainian advances further west.
Kyiv-based military analyst Oleh Zhdanov noted that Kharkiv city and region have also come under heavy attacks, which damaged a regional gas pipeline.
Kharkiv Mayor Ihor Terekhov said in a Telegram post that the city has come under attack twice, presumably from Iranian Shahed drones, five of which Ukraines eastern air command separately reported downing over the city of Dnipro.
Reuters was unable to verify battlefield reports. REUTERS More On This Topic Attacks complicate Russias campaign of striking Ukraines energy grid The war in Ukraine must end soon
