The head of UK secret intelligence said that Putin planned to execute people in parts of Ukraine that were occupied by Russian forces.

Richard Moore, the head of MI6, said in a statement that mass killing was a part of Putin's invasion plans.

The comments tie Putin to the atrocities that have been alleged by the Ukrainians.

Russia has been accused of genocide and war crimes by the international community.

Several people were lying dead on the streets and mass graves. Local residents said the victims were killed by Russian soldiers.

Some of the victims were shot in the head with their hands tied behind their back, and women were raped before they were killed, according to an adviser to the president. He said that children are among those killed.

Following the attack, the President of Ukraine said: "Concentrated evil has come to our land." Murderers. People who torture. Rapists. The looters, who call themselves the army, and who deserve death after what they did.

As the allegations emerged, Moore wrote on social media: "We knew Putin's invasion plans included summary executions by his military and intelligence services."

The reports of execution-style killings of civilians emerging from liberated areas are horrifying.

Intelligence officials from the UK, US, and other Western countries have been speaking out about what they think are Russia's invasion plans.

The strategy began with predicting that Russia would invade Ukraine and was meant to pre-empt attempts by Russia to disguise its intentions or shift blame.

Sir Jeremy Fleming, head of the intelligence and cyber agency GCHQ, made an extraordinary intervention about what he called Putin's personal war in Ukraine.

Even though we believe Putin's advisers are afraid to tell him the truth, sand said, "even though we believe the invasion is a strategic miscalculation."

The UK supports the International Criminal Court as it investigates and prosecutes war crimes.

She said that they would not rest until those responsible for atrocities, including military commanders and individuals in the Putin regime, were brought to justice.

Prime Minister Boris Johnson said that the attacks against innocent civilians in Irpin were proof that Putin and his army were committing war crimes in Ukraine.

He promised to starve Putin's war machine with the promise of further sanctions and military support.

She was going to meet her Polish and Ukrainian counterparts in Warsaw Monday and Tuesday.

She said that Putin was yet to show he was serious about diplomacy.

The victims of sexual violence and those in need of humanitarian support will be supported.
