Russia's defense ministry said on Saturday it had destroyed a large underground depot for missiles and aircraft ammunition in Ukraine's Ivano-Frankivsk region using hypersonic missiles, the Interfax news agency reported.

The ministry said it had also destroyed Ukrainian military radio and reconnaissance centers near the port city of Odessa using a coastal missile system, Interfax reported.

Reuters was not able to independently verify the ministry's statements.

Meanwhile, Ukraine hopes to evacuate civilians on Saturday via ten humanitarian corridors from cities and towns on the front line of fighting with Russian forces.

Deputy Prime Minister Iryna Vereshchuk said a corridor had been agreed for the besieged city of Mariupol, although the authorities' previous efforts to evacuate civilians there under a temporary ceasefire have mostly failed, with both sides trading blame.

Also Saturday, the Ukrainian military imposed a 38-hour curfew in the southern city of Zaporizhzhia, starting at 1400 GMT, deputy mayor Anatoliy Kurtiev said.

"Do not go outside at this time!" he said in an online post.

The regional capital has become an important point of transit for some of the 35,000 people estimated to have Mariupol city in the southeast.
