Ukrainian Foreign Minister Dmytro Kuleba has called on the International Criminal Court (ICC) to head to Bucha, northeastern Ukraine to investigate war crimes committed by Russian forces after they discovered “mass graves.”

Ukraine authorities have found  scenes “hard to describe” with dead bodies of “executed civilians” and “mass graves” in areas that have been liberated from Russian control.

Russian forces have “executed” civilians in Bucha with their hands tied behind their backs and were shot dead “in the back of their heads” which “looks exactly like war crimes.”

Dmytro Kuleba said that the “Bucha massacre was deliberate. Russians aim to eliminate as many Ukrainians as they can.”

The press service of the Ministry of Foreign Affairs of Ukraine quoted the words of Kuleba, said by him on the air of the British radio Times UK radio, on Sunday.

Kuleba said, “I call on the International Criminal Court and international organizations to send their missions to Bucha and other liberated cities and villages of Kyiv region, in order, in cooperation with Ukrainian law enforcement officers, to collect as thoroughly as possible all the evidence of Russian war crimes.”

“We are still collecting and looking for bodies, but the number has already gone to hundreds. Dead bodies lie on the streets. They killed civilians while in these villages and cities, and also leaving them,” Kuleba added.

He also said that Russian forces are guilty of mass crimes in Ukraine, which includes “murder, torture, looting, rape.”

He added, “It was impossible to imagine this in the 21st century, but it is happening before our eyes. Russia is worse than ISIS.”

“If earlier I said that I would make every effort to bring the perpetrators to justice, now I am convinced that this is my life’s work, which I will deal with until my last breath, until they all bear responsibility,” the Minister concluded.

British Foreign Secretary Liz Truss said in a statement the government is “seeing increasing evidence of appalling acts by the invading forces in towns such as Irpin and Bucha.”

She said the “indiscriminate attacks against innocent civilians… must be investigated as war crimes.

“We will not allow Russia to cover up their involvement in these atrocities through cynical disinformation and will ensure that the reality of Russia’s actions are brought to light.”
