Ukraine says all women, children now evacuated from Mariupol steel mill

Russian forces backed by tanks and artillery tried again on Saturday to storm Azovstal, seeking to dislodge the last Ukrainian defenders in the strategic port city on the Azov Sea, Ukraine's military command said.

Weeks of Russian bombardment have left Mariupol in ruins. The steel mill has been largely destroyed. During pauses in fighting, evacuations of civilians began last weekend, brokered by the United Nations and the International Committee of the Red Cross.

Russian-backed separatists have also reported a total of 176 civilians evacuated from the plant. It was not clear if civilian men were still there.

In Washington, U.S. Central Intelligence Agency Director William Burns said Russian President Vladimir Putin is convinced "doubling down" on the conflict will improve the outcome for Russia.

"He's in a frame of mind in which he doesn't believe he can afford to lose," Burns said at a Financial Times event.

Putin declared victory in Mariupol on April 21, ordered the plant sealed off and called for Ukrainian forces inside to disarm. Russia later resumed its assault.

Moscow calls its actions since Feb. 24 a "special military operation" to disarm Ukraine and rid it of anti-Russian nationalism fomented by the West. Ukraine and the West say Russia launched an unprovoked war.

In Kyiv on Saturday, the World Health Organization said it had documented 200 attacks on healthcare facilities in Ukraine, the latest allegations of war crimes by Russian forces. Russia has denied attacking civilian targets.

Mariupol, which lies between the Crimean Peninsula seized by Moscow in 2014 and parts of eastern Ukraine taken by Russia-backed separatists that year, is key to linking the two Russian-held territories and blocking Ukrainian exports.

The Russian defence ministry did not immediately respond to a request for comment about the alleged bombing.

Zelenskiy in his address expressed outrage over Russian shelling overnight that destroyed a museum dedicated to the 18th century philosopher and poet Hryhoriy Skovoroda in the village of Skovorodynivka near Kharkiv.

Other Russian attacks near Kharkiv, Ukraine's second biggest city, blew up three road bridges to slow counter-offensive actions, the Ukrainian military's general staff said.

Russia's defence ministry said it destroyed a large stockpile of military equipment from the United States and European countries near the Bohodukhiv railway station in the Kharkiv region.

Russian forces hit 18 Ukrainian military facilities overnight, including three ammunition depots in Dachne, near the southern port city of Odesa, the ministry said.

Reuters could not independently verify either side's statements about battlefield events.

Russia's lower house of parliament speaker Vyacheslav Volodin accused Washington of coordinating military operations in Ukraine, which he said amounted to direct U.S. involvement in military action against Russia.

US officials have said the United States has provided intelligence to Ukraine to help counter the Russian assault, but have denied this intelligence includes precise targeting data.

Washington and European members of the transatlantic NATO alliance have supplied Kyiv with heavy weapons, but say they will not take part in the fighting.

A senior Russian commander said last month Russia planned to take full control of southern Ukraine to improve Russian access to Transdniestria, a breakaway region of Moldova.

Pro-Russian separatists in Moldova said Transdniestria was hit four times by suspected drones overnight near the Ukrainian border.

Ukraine has repeatedly denied any blame for the incidents, saying it believes Russia is staging the attacks to provoke war. Moscow, too, has denied blame.
