Russia's all-night drone attack on Kyiv injures 23; Trump to speak with Zelenskyy

Russia pummeled Kyiv with drones in an all-night attack, injuring at least 23 people, damaging railway infrastructure and setting buildings and cars on fire throughout the city, authorities in the Ukrainian capital said early on Friday.

Air raid alerts lasted more than eight hours overnight with several waves of attacks, as Russia launched a total of 539 drones and 11 missiles targeting the Ukrainian territory, Ukraine's Air Force said.

"The main target of the strikes was the capital of Ukraine, the city of Kyiv!" the Air Force said in a post on messaging app Telegram.

Fourteen of the injured were hospitalized, said Kyiv's mayor Vitali Klitschko on Telegram.

Damage was recorded in six of Kyiv's 10 districts on both sides of the Dnipro River bisecting the city and falling drone debris set a medical facility on fire in the leafy Holosiivskyi district, according to Klitschko.

The attacks were the latest in a series of Russian air strikes on Kyiv that have intensified in recent weeks and included some of the deadliest assaults of the conflict on the city of three million people.

Ukraine's state-owned railway Ukrzaliznytsia, the country's largest carrier, said on Telegram that the attack on Kyiv damaged railway infrastructure in the city, diverting a number of passenger trains and causing delays.

Ukraine's Air Force said that it had destroyed 478 of the air weapons Russia launched overnight. Enemy air strikes were recorded in eight locations across the country with nine missiles and 63 drones, it added.

Late on Thursday, Russian shelling killed five people in and near the eastern Ukrainian city of Pokrovsk, a key target under Russian attack for months, Ukraine said.

U.S. President Donald Trump said that he had a phone call with Russian President Vladimir Putin on Thursday on efforts to end the crisis in Ukraine, while the Kremlin reiterated that Moscow would keep pushing to solve the conflict's "root causes."

"I'm very disappointed with the conversation I had today with President Putin, because I don't think he's there, and I'm very disappointed," said Trump, adding that the phone call didn't make any progress. 

"I'm just saying I don't think he's looking to stop, and that's too bad."

After speaking to Putin, Trump said he plans to speak to Ukrainian President Volodymyr Zelenskyy, in remarks to reporters on his return to Washington from a trip to Iowa.

Zelenskyy said on Thursday that he hopes to speak with Trump on Friday about the supply of U.S. weapons.

The Trump administration has halted part of military aid to Ukraine following a review of U.S. own stockpiles, the White House and Pentagon confirmed on Tuesday.

"This decision was made to put America's interests first following a review of our nation's military support and assistance to other countries across the globe," White House spokesperson Anna Kelly said in a statement.
