Good evening from Ukraine.

A senior American defense official said something remarkable today about the war going into

week four.

Russian forces, this official said, have made, quote, limited to no progress in achieving

their objectives.

Limited to no progress, nearly 21 days in.

Now, at the same time, nothing about that assessment in any way diminishes the kind of destruction,

even a bogged down army can do, or the threat it poses to human life.

Both are considerable and could even be growing.

Four people were killed today that we know of according to Kiev's mayor in the shelling

of a 60-in-story apartment building, one of at least four that were hit to the northeast

and west of the city center, all within the space of an hour today.

The capital, Kiev, is now under a nighttime curfew, which began earlier today.

In Mariapol, new images of utter devastation.

This video showing just a portion of the destruction from what the mayor said was upwards of

a hundred bombs falling on the city just yesterday alone.

Listen to what a local lawmaker Tolstoynens Jake Tapper earlier tonight.

In Mariapol, people are living in hell.

And situation in Mariapol are catastrophic.

Putin's men are get all the Mariapol citizens like hostages.

And when we tell about Russian military, near Mariapol, it's not about military men.

It's about the rest because they understand that they can get Mariapol with their troops.
