At least 100 civilians remain in Azovstal steelworks - Ukrainian official

The sprawling Azovstal steelworks in the devastated Ukrainian port city of Mariupol still has at least 100 civilians trapped there, according to an aide to the city's mayor.

The civilians' presence "does not reduce the density of attacks by occupiers", mayoral aide Petro Andryushchenko is quoted as saying on messaging app Telegram by Reuters news agency.

The steel plant, which Russia has been attacking for weeks, is under heavy fire.

Fighters from the Azov battalion trapped inside have vowed not to surrender to Russia.
