Officials previously said 17 people were injured in the attack on a children's hospital in Mariupol.
At least three people were killed, including a young girl, in an attack Wednesday on a children's hospital in Mariupol in southern Ukraine, local officials said on Thursday.
"Three people were killed, including a female child, in yesterday's attack on a children's and maternity hospital in Ukraine's besieged Mariupol, according to updated figures this morning," the city council said on its Telegram channel.
Officials had previously given a toll of 17 injured, including doctors, in the attack.
"The Russian forces are destroying Mariupol's civilian population deliberately and without mercy," the city council said.
It says 1,200 inhabitants have been killed in nine days of Russian siege.
The attack on the children's hospital, described by Ukrainian President Volodymyr Zelensky as a "war crime", has triggered international indignation.
Save the Children's Eastern Europe Director, Irina Saghoyan, said in a statement on Thursday: "It's horrifying that a place people seek for help has become one of absolute and utter destruction.
"Where can families and children turn to if even hospitals are not safe? They must not become the battlefields where conflicts rage and innocent children are the casualties."
