Shmyhal reported this on Telegram, according to Ukrinform.
"We visited Bucha. I showed European Commission President Ursula von der Leyen, EU High Representative Josep Borrell and Slovakia's Prime Minister Eduard Heger the atrocities committed by the Russian military against Ukrainian civilians," Shmyhal said.
He said that Ukrainians will never forgive the enemy for these crimes. "We are working together with our European partners to stop the aggressor as soon as possible," he added.
Ursula von der Leyen and Josep Borrell arrived in Kyiv on April 8.
The towns of Irpin, Bucha, Hostomel and the entire Kyiv region were liberated from Russian invaders in early April. Mass killings of civilians by Russians were recorded in liberated towns and villages.
Currently, the bodies are being exhumed from mass graves.
