There will be no evacuation corridors for civilians in Ukraine on Wednesday, the country's Deputy Prime Minister Iryna Vereshchuk said in a statement.
Vereshchuk blamed Russian troops for creating a dangerous situation along the routes.
"Unfortunately, we do not open them today," she said. "In Zaporizhzhia region, the occupiers blocked evacuation buses, and in Luhansk region, they are violating the ceasefire."
Vereshchuk said Russian forces "not only disregard the norms of international humanitarian law, but they also cannot properly control their people on the ground."
"All this creates such a level of danger on the routes that we are forced to refrain from opening humanitarian corridors today," she said.
