Podolyak says Russia continues to shell Mariupol, calls for ceasefire.

Mykhailo Podolyak, advisor to the Ukrainian presidential administration, said in a Tweet on April 24 that “Russia is constantly attacking Mariupol’s Azovstal,” a steel plant sheltering residents. Podolyak urged Russia to open a humanitarian corridor, as well as for a “special round of negotiations” to enable the evacuation of troops and civilians.
