Russia declared a ceasefire and has proposed the establishment of humanitarian corridors to allow civilians to leave five Ukrainian cities including the capital Kyiv from 9 a.m. local time (0700 GMT) on Tuesday pending Ukrainian agreement, the country's Ministry of Foreign Affairs says in a statement.

Civilians leaving the cities of Kyiv, Chernigov and Kharkiv would travel to Russia, some via Belarus, Interfax news agency reported, citing a statement by a Russian committee charged with humanitarian coordination in Ukraine.
