Twenty-three people remain hospitalized Wednesday in the Russian city of Kazan following a school shooting that killed nine people, seven of whom were children.
The attack occurred Tuesday morning when a gunman opened fire on a school there.
"We have lost seven children ... four boys and three girls," Rustam Minnikhanov, the president of the Republic of Tatarstan, told state TV, according to Reuters.
Authorities have said all 23 wounded remain in stable condition and at least eight — three adults and five children — will be transferred to Moscow for further treatment.
Russian officials have promised to pay 1 million rubles to each of the families of those killed and said the payments will be wired by the end of day Wednesday.
Wednesday was declared a day of mourning in Tatarstan, the region where Kazan is the capital.
The attacker has been identified as a 19-year-old and has been arrested. No details were given by authorities regarding a motive.
Russian media has said the gunman was a former student at the school, who called himself "a god" on his Telegram messaging account and promised to "kill a large amount of biomass" on the morning of the shooting.
Russian lawmaker Alexander Khinshtein said on Telegram that the suspect received a permit for a shotgun less than two weeks ago, and the school he targeted had no security besides a panic button.
Attacks on schools are rare in Russia, and Russian President Vladimir Putin ordered the head of the country's National Guard to revise regulations on the types of weapons available for civilian use.
