LVIV, March 12 (Reuters) - Several humanitarian corridors out of Ukrainian towns and villages including from the besieged southern port of Mariupol will be open on Saturday so civilians can leave, Ukraine's Deputy Prime Minister Iryna Vereshchuk said, adding she hoped Russia would observe a ceasefire to allow this to take place.

She said Ukraine plans to evacuate residents of several towns and villages in the regions of Kyiv and inshot Sumy and some other areas where there is ongoing combat.

"I hope that the day will go well, all the planned routes will be open and Russia will fulfill its obligations to guarantee the ceasefire regime," Vereshchuk said in a video address.

Efforts to provide safe passage for residents of Mariupol have repeatedly failed this week.
