According to Ukrinform, Yermak said this in a statement on Telegram.
"Together with the U.S. President's National Security Advisor, Jake Sullivan, we laid flowers at the Wall of Remembrance of the Fallen for Ukraine on Mykhailivska Square in Kyiv and honored the memory of the fallen heroes with a moment of silence," Yermak wrote.
Yermak and Sullivan also visited St. Michael's Golden-Domed Monastery and Volodymyrska Hill.
"No one will be forgotten. There will be revenge for all crimes committed by the Russians, for every lost life of a Ukrainian," Yermak said.
On November 4, as part of his visit to Ukraine, Sullivan met with the military and President Volodymyr Zelensky. He was informed about the situation on the front lines, the implementation of the Black Sea Grain Initiative and Russia's strikes on critical infrastructure.
