All 23 were in stable condition Wednesday morning, the authorities said, though at least eight people were to be transferred to Moscow for treatment.

A gunman on Tuesday morning launched an attack on a school in Kazan, a city 430 miles (700 kilometers) east of Moscow, sending students hiding under their desks or running out of the building. Nine people — seven students and two school employees — were killed. The 19-year-old attacker has been arrested.

Wednesday was declared a day of mourning in Tatarstan, the Russian region of which Kazan is the capital.
