Corridors for civilians to leave Mariupol set up with imminent attack expected

The separatist forces in Donetsk say they have established two corridors for the evacuation of civilians from Mariupol, an indication that a large attack on the key Azov Sea port could be imminent.

Mariupol, an industrial centre, is seen as a key target for Russian forces for its economic value and its location.

Its capture would help Russia establish a land corridor between Crimea and the Russian mainland.
