LVIV, Ukraine — Nights are spent huddling underground from Russian strikes pounding their encircled city into rubble. Daylight hours are devoted to hunting down drinkable water and braving the risk of standing in line for the little food available as shells and bombs rain down.

In the second month of Russia’s invasion, this is what now passes for life in Chernihiv, a besieged city in northern Ukraine where death is everywhere.

It isn’t – yet – quite as synonymous with atrocious human suffering as the pulverized southern city of Mariupol. But similarly blockaded and pounded from afar by Russian troops, Chernihiv’s remaining residents are terrified that each blast, bomb and body that lies uncollected on the streets ensnares them in the same macabre trap of unescapable killings and destruction.

“In basements at night, everyone is talking about one thing: Chernihiv becoming (the) next Mariupol,” said 38-year-old resident Ihar Kazmerchak, a linguistics scholar.

He spoke to The Associated Press by cellphone, amid incessant beeps signaling that his battery was dying. The city is without power, running water and heating. At pharmacies, the lists of medicines no longer available grow longer by the day.

Kazmerchak starts his day in long lines for drinking water, rationed to 2 1/2 gallons per person. People come with empty bottles and buckets for filling when water-delivery trucks make their rounds.

“Food is running out, and shelling and bombing doesn’t stop,” he said.

Nestled between the Desna and Dnieper rivers, Chernihiv straddles one of the main roads that Russian troops invading from Belarus used Feb. 24 for what the Kremlin hoped would be a lightning strike onward to the capital, Kyiv, which is just 91 miles away.

The city’s peace shattered, more than half of the 280,000 inhabitants fled, according to the mayor, unable to be sure when they’d next see its magnificent gold-domed cathedral and other cultural treasures, or even if they still would be standing whenever they return. The mayor, Vladyslav Atroshenko, estimates Chernihiv’s death toll from the war to be in the hundreds.

Russian forces have bombed residential areas from low altitude in “absolutely clear weather” and “are deliberately destroying civilian infrastructure: schools, kindergartens, churches, residential buildings and even the local football stadium,” Atroshenko told Ukrainian television.

On Wednesday, Russian bombs destroyed Chernihiv’s main bridge over the Desna River on the road leading to Kyiv; on Friday, artillery shells rendered the remaining pedestrian bridge impassable, cutting off the last possible route for people to get out or for food and medical supplies to get in.

Refugees from Chernihiv who fled the encirclement and reached Poland this week spoke of broad and terrible destruction, with bombs flattening at least two schools in the city center and strikes also hitting the stadium, museums and many homes.

They said that with utilities knocked out, people are taking water from the Desna to drink and that strikes are killing people while they wait in line for food. Volodymyr Fedorovych, 77, said he narrowly escaped a bomb that fell on a bread line he had been standing in just moments earlier. He said the blast killed 16 people and injured dozens, blowing off arms and legs.

So intense is the siege that some of those trapped cannot even muster the strength to be afraid anymore, Kazmerchak said.

“Ravaged houses, fires, corpses in the street, huge aircraft bombs that didn’t explode in courtyards are not surprising anyone anymore,” he said. “People are simply tired of being scared and don’t even always go down to the basements.”

With the invasion now in its second month, Russian forces have seemingly stalled on many fronts and are even losing previously taken ground to Ukrainian counterattacks, including around Kyiv. The Russians have bombed the capital from the air but not taken or surrounded the city. U.S. and French defense officials say Russian troops appear to have adopted defensive positions outside Kyiv.

With Russia continuing to strike and encircle urban populations, from Chernihiv and Kharkiv in the north to Mariupol in the south, Ukrainian authorities on Saturday dismissed statements from the Russian military suggesting that it planned to concentrate its remaining strength on wresting the entirety of Ukraine’s eastern Donbas region from Ukrainian control. The region has been partially controlled by Russia-backed separatists since 2014.

“We cannot believe the statements from Moscow because there’s still a lot of untruth and lies from that side,” Markian Lubkivskyi, an adviser to the Ukrainian defense minister, told the BBC. “That’s why we understand the goal of (Russian President Vladimir) Putin still is the whole of Ukraine.”

That skepticism was underscored hours later when explosions rocked Lviv, a city in western Ukraine about 45 miles from the Polish border where an estimated 200,000 displaced Ukrainians have taken refuge.

Among them is Olana Ukrainets, a 34-year-old IT worker from Kharkiv.

“When I came to Lviv, I was sure that all these alarms wouldn’t have any results,” Ukrainets told the AP from a bomb shelter after the blasts. “Sometimes when I heard them at night, I just stayed in bed. Today, I changed my mind and I should hide every time. … None of the Ukrainian cities are safe now.”

The strike happened as President Biden was visiting Poland, which has taken in far more Ukrainian refugees than any other country.

Britain’s defense ministry said Saturday that it doesn’t expect a reprieve for citizens of Ukraine’s bombarded cities anytime soon.

“Russia will continue to use its heavy firepower on urban areas as it looks to limit its own already considerable losses, at the cost of further civilian casualties,” the U.K. ministry said.

Previous bombings of hospitals and other nonmilitary sites, including a theater in Mariupol where Ukrainian authorities said a Russian airstrike is believed to have killed 300 people last week, already have given rise to war crimes allegations.

Ukrainian President Volodymyr Zelensky, appearing by video link at Qatar’s Doha Forum, on Saturday compared the destruction of Mariupol to the Syrian and Russian destruction wrought on the city of Aleppo.

Later, in a video address, Zelensky assailed Russian claims that Ukraine is trying to wipe out the use of the Russian language, saying: “You are doing everything so that our people themselves leave the Russian language, because the Russian language will now be associated only with you, with your explosions and murders, your crimes.”

The invasion has driven more than 10 million people from their homes, almost a quarter of Ukraine’s population. Of those, more than 3.7 million have fled the country entirely, according to the United Nations. Thousands of civilians are believed to have died.

In Chernihiv, hospitals are no longer operating, and residents cook over open fires in the street because the power is out. The utility workers who stayed behind aren’t enough to repair the broken powerlines and restore other essential services, and time has become a blur, the mayor said.

“We live without dates and days of the week,” Atroshenko told Ukrainian television.

Ever since a Russian blast hit a Stalin-era movie theater next to his 12-story residential building, Kazmerchak, the linguistics scholar, has been spending his nights in a bomb shelter. A Russian missile also destroyed the hotel not far from his house.

“The walls were shaking so much,” he said. “I thought my house would collapse any minute and I would be left under the rubble.”
