Senate Speaker Małgorzata Kidawa-Błońska and Deputy Speaker of the Sejm lower house Monika Wielichowska are attending the Bucha Summit, a gathering convened by Ukrainian parliament speaker Ruslan Stefanchuk and drawing senior representatives from across Europe.
Kidawa-Błońska warned against letting the war in Ukraine fade from public attention amid other global crises.
"As long as Ukraine is fighting, we can feel safe – it is holding Russia back," she said, adding that those responsible for the killings "will be punished, because this was genocide."
She also called for accountability over the deportation of Ukrainian children to Russia, describing it as a separate crime that must not go unanswered.
Wielichowska said the summit was not only about remembrance.
"We are going to Bucha to remember, but we are also thinking about tomorrow, about Ukraine's future and the future of its coming generations."
Ukraine's EU integration is among the topics on the agenda.
Russian forces occupied Bucha for 33 days from early March 2022.
After Ukrainian troops retook the town in April of that year, the scale of the killings shocked the world.
Ukrainian prosecutors say more than 400 civilians were killed in and around Bucha during the occupation, including 37 children.
Bodies were found on streets and in basements, many with gunshot wounds to the head and hands bound behind their backs.
