Both sides have been burying their dead as Ukraine slides further towards war, with supporters of Russia and of a united Ukraine each accusing the other side of tearing the country apart.
Tuesday morning was quiet in eastern and southern Ukraine, but the deadliest few days since the separatist uprising began have transformed the conflict, hardening positions and leaving little room for peaceful resolution.
In Kramatorsk, a separatist-held town in the east that saw an advance by Ukrainian troops at the weekend, the coffin of 21-year-old nurse Yulia Izotova was carried through streets stilled by barricades of tyres and tree trunks. Scattered red carnations traced the route.
At the Holy Trinity Church, seven priests led mourners in prayer for a woman killed by large calibre bullets, which the townsfolk believe were fired by Ukrainian troops.
"They shoot at us. Why? Because we don't want to live with fascists?" asked 58-year-old passport photographer Sergei Fominsky, standing with his wife among the mourners. "We're not slaves. We kneel to no one."
In Odessa, a previously peaceful, multi-ethnic Black Sea port where more than 40 people were killed on Friday in the worst day of violence since a February revolt toppled Ukraine's pro-Russian president, pall-bearers carried the open casket of Andrey Biryukov from a van to the street corner where he was shot.
A pro-Ukrainian activist, Biryukov, 35, was killed during a day that began with hundreds of pro-Russian sympathisers armed with axes, chains and guns attacking a Ukrainian march, and ended later that night with the pro-Russians barricaded inside a building that was set on fire, killing dozens.
A small crowd of about 50 stood around the body, covering it with carnations and roses. A Ukrainian flag fluttered in the wind, and a patriotic song about dead heroes was played from a sound system.
Relatives wept and a young woman fell on her knees crying loudly. The corner where the man died was decorated with flowers and small Ukrainian flags.
"The government has failed to protect its own people. The police have failed miserably," said Nikita, a grizzled 56-year-old with a Ukrainian yellow and blue arm-band.
Sergei, in his 40s, who also came to mourn, said violence "was imported to Odessa".
"We were proud of Odessa as a unique place where people used to live in peace, regardless of their beliefs and religion and race," he said. "Now this is all gone."
The past few days have seen government forces press on with an offensive in the east, where separatist rebels have so far held firm at their main outpost in the town of Slaviansk and shot down three Ukrainian military helicopters.
Interior Minister Arsen Avakov said on Tuesday more than 30 separatists had been killed in fighting around Slaviansk, but there was no confirmation of such a figure. The rebels, who triggered fighting in the area on Monday by ambushing government troops, said four of their number had been killed.
The Ukraine crisis has led to a confrontation between Moscow and the West unseen since the darkest days of the Cold War.
Since a pro-European government took power after the uprising that toppled pro-Russian President Viktor Yanukovich in February, Russian President Vladimir Putin overturned decades of diplomacy by declaring Moscow's right to intervene to protect Russian speakers in the neighbouring former Soviet republic.
In March, Russia seized and annexed Ukraine's Crimea region, and in the weeks that followed, armed separatists have taken control of most of the eastern Donbass coal and steel region, which accounts for around 15 percent of Ukraine's the population and a third of industrial output.
Moscow has tens of thousands of troops massed on Ukraine's eastern frontier. The outbreak of violence in Odessa, hundreds of kilometres away near a Russian-occupied breakaway region of neighbouring Moldova, means the unrest has spread across the breadth of southern and eastern Ukraine.
Western countries say Russian agents are directing the uprising and Moscow is stoking the violence with a campaign of propaganda, beamed into Ukraine on Russian state channels, that depicts the government in Kiev as "fascists".
"Russia sometimes sounds as if it's refighting WW2. Fascism all over the place. Enemies everywhere. Ghosts of history mobilised," tweeted Swedish Foreign Minister Carl Bildt.
Germany struck an even more ominous note.
"The bloody pictures from Odessa have shown us that we are just a few steps away from a military confrontation," German Foreign Minister Frank-Walter Steinmeier warned in interviews published in four European newspapers.
However, so far Western anger has not been matched by any serious action that might dissuade Putin. The United States and the European Union have imposed limited sanctions on lists of individual Russians and small firms, but have held back from measures designed to hurt Russia's economy broadly.
NATO has made clear it will not fight to protect Ukraine, instead beefing up defences of its nearby member states. NATO's top military commander, U.S. Air Force General Philip Breedlove, said on Monday Russia was deploying special forces in eastern Ukraine and he now believed Moscow might be able to achieve its goals without resorting to a conventional invasion.
Western leaders have threatened to impose tougher sanctions on Russia if it interferes with presidential elections in Ukraine set for May 25, and most of their diplomacy has been centred around that date.
"If (the election) doesn't take place, there will be chaos and the risk of civil war," French President Francois Hollande said. "The Russians, Vladimir Putin, at the moment want this election not to happen so as to maintain the pressure. It's up to us to convince them."
Petro Poroshenko, a Ukrainian confectionery baron who is front-runner in the presidential election, said the vote would go ahead despite the unrest:
"We hope that we will be able to complete the anti-terrorist operation before the election. And where we cannot do so - we will surround (those places) and not allow them to interfere with the election."
But that deadline could be too late to prevent Ukraine from being dismembered: separatists in the Donbass region say they will hold a referendum on secession two weeks earlier, on Sunday, similar to the one that preceded Russia's annexation of Crimea.
