“The enemy targeted our depots” but “we have no information of the type of missile,” Ukrainian Air Force spokesman Yuri Ignat said.

“There has been damage, destruction and the detonation of munitions,” he said.

A U.S. official said Russia’s offensive remains largely stalled overall, with troops about 30 km east of the capital Kyiv and facing heavy resistance.

Britain’s Defence Ministry said Russia was struggling to provide its forward troops “with even basic essentials such as food and fuel” because of Ukrainian attacks on their supply lines.

But as in previous negotiations there appeared to be little progress in reaching a ceasefire, with Russian President Vladimir Putin accusing Ukraine of “numerous war crimes” during a call late on Friday with his French counterpart Emmanuel Macron.

British Foreign Secretary Liz Truss accused Moscow of using the talks as a ‘smokescreen’ as it carried out “appalling atrocities,” saying she was “very sceptical” they would produce a breakthrough.

As Mr. Putin’s ground offensive has met with fierce resistance, Moscow has increasingly turned to indiscriminate air and long–range strikes. Friday’s attack on the arms depot was the latest strike in western Ukraine.

More than 3.25 million refugees have fled Ukraine and countless others have sought havens in the country’s west, though Mr. Putin said his forces were doing “everything possible” to avoid civilian casualties. But Mr. Zelensky accused Russian forces of blocking aid around hotspot areas.

Russia wants Ukraine to disarm and disavow all Western alliances — steps that Kyiv says would turn it into a vassal state of Moscow.
