Multiple humanitarian routes were opened on Wednesday, as the leader warned Russian troops against violating the ceasefire - as has been the pattern in recent days.
"We have a short window of time at the moment (for evacuations). Even if there is a ceasefire right now, there is a high risk of shells falling at any moment," warned Yevhen Nyshchuk, Ukraine's former culture minister, now fighting with the territorial defence forces.
The first major evacuation from a Ukrainian city under attack appeared to be successful on Tuesday, after a safety corridor for civilians fleeing Sumy allowed thousands to leave.
Concerns remain, however, for several other key areas in the country - particularly Mariupol which is facing a worsening humanitarian disaster having been cut off from food, water, and medical supplies.
