The overnight bombardment was the first since US President Donald Trump announced the 'energy ceasefire' at the weekend, and Ukrainian energy facilities appeared to have been spared for the first time since that announcement of a russia ukraine energy ceasefire.

Russian forces nonetheless struck cities' transport and logistics links with ballistic missiles and drones. At least four people died in Kharkiv, Ukraine's second city, and at least a dozen were injured across the country, according to Ukrainian officials.

Cities hit as energy facilities spared

Russia's defence ministry, summarising the overnight attacks, did not list any Ukrainian energy facilities among the targets. The Ukrainian air force said damage was recorded at 17 locations, and that its units shot down 88 of the 108 drones Russia launched.

• •In Kharkiv, four people died and at least 11 were hurt in a residential building; regional officials also reported damage to a hospital in the western Khmelnytskyi region
• •A cargo terminal in the southern Mykolaiv region and transport infrastructure in the southeastern Dnipropetrovsk region were hit
• •One missile landed just over a kilometre from a plant that heats much of the western city of Lviv

The overnight restraint on energy targets followed Monday, when Russia struck six Ukrainian energy sites.

Missing warnings before missiles on Kyiv

Six ballistic missiles were fired at Kyiv late Monday, and the Ukrainian air force said it had received no prior surveillance warnings before the launch. "The causes are being investigated," the air force said in a statement.

Warnings about preparations for ballistic missile attacks have been part of the intelligence the US shares with Ukraine, according to Ukrainian officials. Foreign Minister Andrii Sybiha said on Tuesday that this flow of data from Washington continues.

Washington's diesel deal and pressure on Kyiv

Trump announced the ceasefire on Sunday, two days after a deal lifting US sanctions on Russian diesel exports to allow supply of almost 2 million metric tons, aimed at lowering US fuel prices.

Media, including Reuters, reported that US officials threatened to cut off intelligence sharing and weapons sales to Ukraine unless it halts strikes on Russian oil refineries.

Trump has blamed Ukrainian attacks, which prompted Moscow to suspend diesel exports, for a rise in US diesel prices ahead of Congressional midterm elections in three weeks. Most analysts say Trump's war in Iran had a far greater impact on the diesel price rise.

What each side says the ceasefire means

President Volodymyr Zelensky said Tuesday that Ukrainian strikes on Russian refineries had stopped for two days, since Trump announced the ceasefire, while Russian attacks on energy and critical infrastructure went on. Kyiv backs the idea of an energy truce, he said, but accuses Moscow of breaking it - an agreement the Kremlin has never said it joined.

Zelensky, speaking Monday at a security conference in Warsaw, said: "This winter, if Russia does not agree to an energy ceasefire, we will respond."

Sybiha, speaking at the same Warsaw security conference, said the US request to halt attacks on Russian refineries showed Ukraine's position had strengthened, referencing Trump's earlier "you don't have the cards" remark. "In less than two years, we have gone from 'having no cards' to 'not playing your cards'. That is an achievement," Sybiha said.

A Kremlin spokesman, when asked about the truce, would only say that contacts were ongoing, but declined to provide any further details.

Zelensky's office did not immediately respond to requests for comment.
