Russia and Ukraine traded the attacks over the weekend shortly after Russian President Vladimir Putin met with US officials over the ceasefire agreement.
The Associated Press reported that both sides have reported more than 100 enemy drones through the territory.
Putin said Thursday that he supported the ceasefire but outlined many details that need to be negotiated before the deal is completed.
He said that although it is open to a 30-day ceasefire proposed by the US, he provided vague terms for his support and raised questions about what the Kremlin wanted.
British Prime Minister Kiel Starmer challenged Putin to sign up for a ceasefire contract if he was serious about finding peace. He said the allies will continue to increase pressure on Russia.
Ukrainian President Voldimi Zelensky expressed his support for the plan, saying the country would like to work towards a longer, clear ceasefire agreement.
Zelensky has expressed concern about recent Russia's activities, particularly along the border.
Secretary of State Marko Rubio met with Russian Foreign Minister Sergei Lavrov and discussed the next steps after meeting with Ukraine in Saudi Arabia last week.
