Zelenskyy says he expects a 'new wave' of Russia's war on Ukraine — and warns 'whether we will be able to survive' depends on how quickly military aid arrives

• Zelenskyy said he expects "a new wave" of Russia's war to hit eastern and southern Ukraine.
• The Ukrainian president also said 'whether we will be able to survive' depends on how quickly military aid arrives from countries like the US.

Ukrainian President Volodymyr Zelenskyy said he expects his country will soon face "a new wave" of Russia's war on Ukraine.

Zelenskyy recently sat down with CBS News correspondent Scott Pelley in Kyiv for a conversation slated to air on "60 Minutes" on Sunday night. The show posted a clip of their conversation on Twitter early Sunday ahead of broadcasting the full interview.

"We think this will be a new wave of this war," Zelenskyy said, when asked what he expects to see in eastern and southern Ukraine. "We don't know how much Russian weaponry there will be, but we understand there will be many times more than there is now."

Zelenskyy also spoke about the country's urgent need for military aid.

"All depends on how fast we will be helped by the United States," he said. "To be honest, whether we will be able to survive depends on this."

Zelenskyy continued: "I have 100% confidence in our people and in our armed forces, but unfortunately I don't have the confidence that we will be receiving everything we need."

In an interview Friday with German newspaper BILD, which is owned by Axel Springer, Insider's parent company, Zelenskyy said he's unaware of the status of some towns in the east and south of Ukraine.

"We don't have real knowledge on what is going on in the south of our country now or in other small towns around the country. Or in the east of the country," he said.

Zelenskyy added in the interview that fighting in Donbas, an eastern Ukrainian region, could amount to a war "like the world has not seen in hundreds of years."

Iryna Vereshchuk, Ukraine's deputy prime minister, has encouraged Ukrainians living in the east to escape while they can.

In the south, Mariupol Mayor Vadym Boichenko has estimated that at least 5,000 people, including 210 children, have died in the city since Russia began its unprovoked invasion of Ukraine.
