Ukraine's Deputy Prime Minister Iryna Vereshchuk said no humanitarian routes were established out of the southeastern Ukrainian port city of Mariupol on Sunday as Russian forces did not hold their fire.
Vereshchuk said that the Ukrainian side would try again on Monday to establish safe passage out of Mariupol, reports Reuters.
She called for UN Secretary General Antonio Guterres, who is scheduled to travel to Moscow before visiting Kyiv next week, to demand a ceasefire and open up humanitarian corridors from Mariupol.
"This is what Guterres should talk about in Moscow, if he is preparing to talk about peace," Vereshchuk said.
