Heartbreaking satellite images show bodies lining the streets in the Ukrainian town of Bucha while it was still under Russian control - disproving Kremlin lies about being responsible.
The images verify that corpses were lying in the open for weeks before Bucha, on the outskirts of Kyiv, was liberated.
Russian forces are accused of a litany of war crimes including murder, torture and rape, with troops carrying out acts of "unspeakable, deliberate cruelty and violence".
Vladimir Putin's officials tried to claim that Ukraine had killed the innocent people in an act of "provocation" after troops withdrew - but the satellite images expose their callous lies.
Devastating details have emerged of summary executions of civilians - many of who had their hands tied behind their backs - since Bucha was liberated.
At least 410 were killed in and around Bucha, Ukraine said, with President Volodymyr Zelensky describing the slaughter as "genocide".
Yesterday a mass grave of 57 bodies was uncovered in the city.
Pictures taken on March 19 reveal dark objects found in the same places where rotting corpses were found after Russia withdrew.
Private surveillance company Maxar Technologies also uncovered a 45ft trench where a mass grave was found in satellite images.
Maxar spokesman Stephen Wood said in a statement: "High-resolution Maxar satellite imagery collected over Bucha, Ukraine (northwest of Kyiv) verifies and corroborates recent social media videos and photos that reveal bodies lying in the streets and left out in the open for weeks."
The company previously said the first signs of excavation for a mass grave at the Church of St. Andrew and Pyervozvannoho All Saints were seen on March 10.
In a press conference Russian envoy to the UN Vassily Nebenzia falsely tried to pass the blame for the murders on Ukraine.
She claimed the heartbreaking scenes were "arranged by the Ukrainian information, information warfare machine".
Speaking from Bucha, Mr Zelensky vowed that Putin and his troops would be punished for the alleged war crimes.
He said: "It's very difficult to talk. It's very difficult to negotiate when you see what they did here.
"Every day we find people in barrels, cellars and everywhere else, some strangled, some clearly tortured."
He continued to reporters: "These are war crimes and will be recognised by the world as genocide. You are here today and can see what happened.
"We know of thousands of people killed and tortured, with severed limbs, raped women, murdered children. I think it is more than ... this is a genocide."
Earlier today The Mirror reported that the Russian commander behind the atrocities in Bucha has been named and pictured.
Kyiv intelligence sources have named Lt Colonel Azatbek Omurbekov - who leads the 64th Separate Motorised Rifle Brigade which occupied the region - as the commander in the area.
Ihor Zhovkva, deputy head of the office of the President of Ukraine, said Mr Zelensky "will give all the evidence" to the international community at the Security Council meeting.
"If these awful atrocities will not change the agenda of all the world, what will change?" the adviser asked on BBC Radio 4's Today programme.
Mr Zhovkva said Ukraine needs "additional weapons", including tanks and missiles, to "liberate more cities" from Russia control.
Dame Barbara Woodward, Britain's UN ambassador, called images coming from Bucha "harrowing, appalling, probable evidence of war crimes and possibly a genocide".
She cited hundreds of bodies being dumped in the streets or in mass graves and allegations of rape.
