LVIV, Ukraine (AP) 鈥� The humanitarian crisis in Ukraine deepened Monday as Russian forces intensified their shelling and food, water, heat and medicine grew increasingly scarce, in what the country condemned as a medieval-style siege by Moscow to batter it into submission.
A third round of talks between the two sides ended with a top Ukrainian official saying there had been minor, unspecified progress toward that would allow civilians to escape the fighting. Russia鈥檚 chief negotiator said he expects those corridors to start operating Tuesday.
But that remained to be seen, given the failure of previous attempts to lead civilians to safety amid the biggest ground war in Europe since World War II.
Well into the second week of the invasion, with Russian troops making significant advances in southern Ukraine but stalled in some other regions, a top U.S. official said multiple countries were discussing whether to provide the warplanes that Ukrainian President Volodymyr Zelenskyy has been pleading for.
Russian President Vladimir Putin鈥檚 forces continued to pummel cities with rockets, and fierce fighting raged in places. In the face of the bombardments, Zelenskyy said Ukrainian forces were showing unprecedented courage.
鈥淭he problem is that for one soldier of Ukraine, we have 10 Russian soldiers, and for one Ukrainian tank, we have 50 Russian tanks,鈥� Zelenskyy told ABC 撸奶社区 in an interview that aired Monday night. He noted that the gap in forces was diminishing and that even if Russian forces 鈥渃ome into all our cities,鈥� they will be met with an insurgency.
In one of the most desperate cities, the encircled southern port of Mariupol, an estimated 200,000 people 鈥� nearly half the population of 430,000 鈥� were hoping to flee, and Red Cross officials waited to hear when a corridor would be established.
The city is short on water, food and power, and cellphone networks are down. Stores have been looted as residents search for essential goods.
Police moved through the city, advising people to remain in shelters until they heard official messages broadcast over loudspeakers to evacuate.
Hospitals in Mariupol are facing severe shortages of antibiotics and painkillers, and doctors performed some emergency procedures without them.
The lack of phone service left anxious citizens approaching strangers to ask if they knew relatives living in other parts of the city and whether they were safe.
In the capital, Kyiv, soldiers and volunteers have built hundreds of checkpoints to protect the city of nearly 4 million, often using sandbags, stacked tires and spiked cables. Some barricades looked significant, with heavy concrete slabs and sandbags piled more than two stories high, while others appeared more haphazard, with hundreds of books used to weigh down stacks of tires.
鈥淓very house, every street, every checkpoint, we will fight to the death if necessary,鈥� said Mayor Vitali Klitschko.
In Kharkiv, Ukraine's second-largest city, with 1.4 million people, heavy shelling slammed into apartment buildings.
鈥淚 think it struck the fourth floor under us,鈥� Dmitry Sedorenko said from his Kharkiv hospital bed. 鈥淚mmediately, everything started burning and falling apart.鈥� When the floor collapsed beneath him, he crawled out through the third story, past the bodies of some of his neighbors.
Klitschko reported that fierce battles continued in the Kyiv region, notably around Bucha, Hostomel, Vorzel and Irpin.
In the Irpin area, which has been cut off from electricity, water and heat for three days, witnesses saw at least three tanks and said Russian soldiers were seizing houses and cars.
A few miles away, in the small town of Horenka, where shelling reduced one area to ashes and shards of glass, rescuers and residents picked through the ruins as chickens pecked around them.
鈥淲hat are they doing?鈥� rescue worker Vasyl Oksak asked of the Russian attackers. 鈥淭here were two little kids and two elderly people living here. Come in and see what they have done.鈥�
In the south, Russian forces also continued their offensive in Mykolaiv, opening fire on the Black Sea shipbuilding center of a half-million people, according to Ukraine鈥檚 military. Rescuers said they were putting out fires caused by rocket attacks in residential areas.
At The Hague, Netherlands, Ukraine pleaded with the International Court of Justice to order a halt to Russia鈥檚 invasion, saying Moscow is committing widespread war crimes.
Russia 鈥渋s resorting to tactics reminiscent of medieval siege warfare, encircling cities, cutting off escape routes and pounding the civilian population with heavy ordnance,鈥� said Jonathan Gimblett, a member of Ukraine鈥檚 legal team.
Russia snubbed the court proceedings, leaving its seats in the Great Hall of Justice empty.
Efforts to set up safe passage for civilians over the weekend fell apart amid continued Russian shelling. Before Monday's talks began, Russia announced a new plan, saying civilians would be allowed to leave Kyiv, Mariupol, Kharkiv and Sumy.
But many of the evacuation routes headed toward Russia or its ally Belarus, which has served as a launch pad for the invasion. Ukraine instead proposed eight routes allowing civilians to travel to western regions of the country where there is no shelling.
Later, Russia鈥檚 U.N. Ambassador, Vassily Nebenzia, told the U.N. Security Council that Russia would carry out a cease-fire Tuesday morning and appeared to suggest that humanitarian corridors leading away from Kyiv, Mariupol, Sumy and Chernigov could give people choice in where they want to go.
The U.N. humanitarian chief, Undersecretary-General Martin Griffiths, addressed the Security Council and urged safe passage for people to go 鈥渋n the direction they choose.鈥�
Zelenskyy鈥檚 office would not comment on the Russian proposal, saying only that Moscow鈥檚 plans can be believed only if a safe evacuation begins. The office said Deputy Prime Minister Iryna Vereshchuk planned to make a statement on the issue Tuesday morning.
The battle for Mariupol is crucial because its capture could allow Moscow to establish a land corridor to Crimea, which Russia seized from Ukraine in 2014.
The fighting has sent , and threatens t of people around the globe who rely on crops farmed in the fertile Black Sea region.
The U.N. human rights office reported 406 confirmed civilian deaths but said the real number is much higher. The invasion .
On Monday, Moscow again announced a series of demands to stop the invasion, including that Ukraine recognize Crimea as part of Russia and recognize the eastern regions controlled by Moscow-supported separatist fighters as independent. It also insisted that Ukraine change its constitution to guarantee it won鈥檛 join international bodies like NATO and the EU. Ukraine has already rejected those demands.
Zelenskyy has called for more punitive measures against Russia, including a global boycott of its oil exports, which are key to its economy.
鈥淚f (Russia) doesn鈥檛 want to abide by civilized rules, then they shouldn鈥檛 receive goods and services from civilization," he said in a video address.
He has also asked for more warplanes. Deputy U.S. Secretary of State Wendy Sherman said officials are "trying to see whether this is possible and doable.鈥�
While the West has been rushing weapons to Ukraine such as anti-tank and anti-aircraft missiles, some officials fear that sending warplanes could be seen by Moscow as direct involvement in the war.
One possible scenario under discussion: Former Soviet bloc nations that are now NATO members could send Ukraine their own Soviet-era MiGs, which Ukrainian pilots are trained to fly, and the U.S. would then replace those countries' aircraft with American-made F-16s.
Russia's invasion has nearby countries terrified the war could spread to them.
U.S. Secretary of State Antony Blinken to the Baltic states of Latvia, Lithuania and Estonia, former Soviet republics that are NATO members. Blinken hoped to reassure them of the alliance鈥檚 protection.
NATO has shown no interest in sending troops into the country and has rejected Zelenskyy's pleas to establish a no-fly zone for fear of triggering a wider war.
