The Russian military is expected to allow humanitarian corridors to be opened in several Ukrainian cities this morning.
Forces are due to hold fire and allow people to escape cities including Kyiv, Kharkiv, Sumy and Mariupol.
Efforts to evacuate around 200,000 people from the heavily bombarded city of Mauriopol failed on Sunday as proposed ceasefires collapsed for the second day in a row.
The city is under near constant shelling with Russian forces cutting off food, water and heating supplies from the city.
Ukraine said Russian shelling was preventing residents from evacuating the area in corridors agreed at the last round of ceasefire talks.
The city council called off a second evacuation attempt on Sunday, saying Russian forces had again broken an agreement to suspend hostilities until the evening.
The International Committee of the Red Cross (ICRC) said the evacuations had failed partly because the two sides had not agreed a clear plan.
The town of Irpin - just outside Kiev - has endured sustained shelling by Moscow's forces.
Some families claim Russians have targeted schools and hospitals, and children have been killed.
Ukrainian President Volodymyr Zelenskyy has warned Russia that instead of forgiveness, it will face a day of judgement.
In his latest video message, President Zelenskyy said: "We will not forgive the destroyed houses. We will not forgive the missile that our air defence shot down over Okhmatdyt today and more than five hundred other such missiles that hit our land in Ukraine, our people, our children.
"We will not forgive the shooting of unarmed people. Destruction of our infrastructure. We will not forgive.
“Hundreds and hundreds of victims. Thousands and thousands suffering and God will not forgive. Not today. Not tomorrow. Never. And instead of forgiveness, there will be a day of judgement."
He said Russia had broken it promise to open humanitarian corridors adding: “Instead of humanitarian corridors, they can only make bloody ones.”
"Today a family was killed in Irpin,” he said. “Man, woman and two children. Right on the road. As in a shooting gallery. When they tried to just get out of the city, to be saved."
More than 1.5 million Ukrainians have fled the country since the invasion began 11 days ago.
The civilian death toll now stands at 364, including more than 20 children, the United Nations said on Sunday.
