Mayor: More than 10,000 civilians dead in Ukraine port city

KYIV, Ukraine (AP) — Corpses are now “carpeted through the streets” of Mariupol after Russian troops killed more than 10,000 civilians over the past six weeks in their unsuccessful fight to capture the strategic southern port, the mayor said, while Western powers warned Tuesday of an ongoing buildup for a suspected Russian assault in Ukraine’s east.

The British Ministry of Defense said Russian forces are continuing to pull out of Belarus to support operations in eastern Ukraine, focused on the Donbas region, where Russian-allied separatists have claimed independence.

“Fighting in eastern Ukraine will intensify over the next two to three weeks as Russia continues to refocus its efforts there,” the ministry said in a tweet. “Russian attacks remain focused on Ukrainian positions near Donetsk and Luhansk with further fighting around Kherson and Mykolaiv and a renewed push toward Kramatorsk.”

The southeastern port city of Mariupol has seen some of the heaviest attacks and civilian suffering in the 6-week-old war, but the land, sea and air assaults by Russian forces fighting to capture it have increasingly limited information on circumstances inside the city.

Speaking by phone Monday with The Associated Press, Mariupol Mayor Vadym Boychenko accused Russian forces of having blocked weeks of attempted humanitarian convoys into the city in part to conceal the carnage. Boychenko said the death toll in Mariupol alone could surpass 20,000.

Boychenko also gave new details of allegations by Ukrainian officials that Russian forces have brought mobile cremation equipment to Mariupol to dispose of the corpses of victims of the siege.

Russian forces have taken many bodies to a huge shopping center where there are storage facilities and refrigerators, Boychenko said.

“Mobile crematoriums have arrived in the form of trucks: You open it, and there is a pipe inside and these bodies are burned,” he said.

Boychenko spoke from a location in Ukrainian-controlled territory but outside Mariupol. The mayor said he had several sources for his description of the alleged methodical burning of bodies by Russian forces in the city, but did not further detail the sources of his information.

The discovery of large numbers of apparently executed civilians after Russian forces retreated from cities and towns around the capital, Kyiv, already has prompted widespread condemnation and assertions that Russia is committing war crimes in Ukraine.

U.S. officials also point to further signs Russia’s military is gearing up for a major offensive in Ukraine’s eastern Donbas region, switching its focus after Russian forces failed in their initial drive to capture Kyiv.

Donbas has been torn by fighting between Russian-allied separatists and Ukrainian forces since 2014, and Russia has recognized the separatists’ claims of independence. Military strategists say Russian leaders appear to hope local support, logistics and terrain in Donbas favor Russia’s larger and better-armed military, potentially allowing Russian troops to gain more territory and weaken Ukraine’s fighting forces.

Russia has appointed a seasoned general to lead its renewed push in the eastern Donbas region.

A senior U.S. defense official on Monday described a long Russian convoy now rolling toward the eastern city of Izyum with artillery, aviation and infantry support, as part of redeployment for what appears to be the looming Russian campaign.

More artillery is being deployed near the city of Donetsk, while ground combat units that withdrew from around the Kyiv and Chernihiv areas appear destined for refitting and resupplying before they position in Donbas, said the official, who spoke on condition of anonymity to discuss internal U.S. military assessments.

With their offensive in many parts of the country thwarted, Russian forces have relied increasingly on bombarding cities — a strategy that has flattened many urban areas and killed thousands of people.

The U.N. children’s agency said nearly two-thirds of all Ukrainian children have fled their homes in the six weeks since Russia’s invasion began. The United Nations has verified 142 children have been killed and 229 injured, though the actual numbers are likely much higher.

Ukrainian authorities accuse Russian forces of committing atrocities, including a massacre in the town of Bucha, outside Kyiv, airstrikes on hospitals and a missile attack that killed at least 57 people last week at a train station.

In Bucha, the work of exhuming bodies from a mass grave in a churchyard resumed.

Galyna Feoktistova waited for hours in the cold and rain in hopes of identifying her 50-year-old son, who was shot and killed more than a month ago, but eventually she went home for some warmth. “He’s still there,” her surviving son, Andriy, said.

In Mariupol, about 120,000 civilians are in dire need of food, water, warmth and communications, the mayor said.

Only those residents who have passed the Russian “filtration camps” are…
