Russia announced yet another cease-fire and a handful of humanitarian corridors to allow civilians to flee Ukraine starting Monday, but previous such measures have fallen apart and Moscow’s armed forces continued to pummel some Ukrainian cities with rockets even after the announcement. A day earlier, hundreds of thousands of civilians attempting to flee to safety were forced to shelter from what Ukrainian officials said was Russian shelling in cities in the center, north and south.

Ahead of a third round of talks planned for Monday, the Russian Defense Ministry said a cease-fire would start in the morning, and safe passages would open for civilians from the capital of Kyiv, the southern port city of Mariupol, and the cities of Kharkiv and Sumy. Some of the evacuation routes, however, would funnel civilians toward Russia or its ally Belarus — unlikely destinations for many Ukrainians who would prefer to head toward countries on the western and southern borders.
