President Donald Trump spoke on Sunday.

He said Russia and Ukraine agreed to an "energy ceasefire."

He gave no details.

He said it started right away.

Moscow did not say anything at first.

Ukrainian President Volodymyr Zelenskyy said Ukraine welcomed the news.

He said it is good for everyone.

But he said Russia still hits energy sites in Kyiv and Kharkiv.

He said Russia attacked a power plant in Kharkiv that evening.

His office said the attack came after Trump's post.

Zelenskyy said Ukraine is ready to stop hitting Russian energy sites.

Russia must do the same.

Trump said a similar thing on Sept. 14.

Nothing happened.

On Saturday, Trump said Ukraine needs a new president.

He blamed Zelenskyy for high U.S. diesel prices.

Zelenskyy said Ukraine can hold elections.

Russia must agree to a 60-day ceasefire.

He said the Ukrainian people choose their leader.

Ukraine has been under martial law since February 2022.

Its constitution bars elections during it.

Ukraine also kept hitting Russian infrastructure.

A drone attack on Sunday shut down a Yandex data center in the city of Vladimir.

It was the third strike on Yandex sites in four days.

The outage stopped taxis and banking for users in many Russian cities.

It also hit Kazakhstan, Belarus and Armenia.

In Zaporizhzhia, rescuers ended work after a Russian bombing Saturday.

Zelenskyy said 23 people were killed.

Four of them were children.
