Mariupol city council showed the courtyard outside of the hospital was badly damaged

Russian forces surrounding the southern port city of Mariupol have destroyed a maternity hospital, Ukraine says.

President Volodymyr Zelensky said children were under the wreckage, and called on Western leaders to impose a no-fly zone.

He also posted footage apparently from inside the hospital, which appears badly damaged.

There is no information yet on casualties, or on who was inside the hospital at the time.
