MOSCOW (AP) — Russia's health minister says at least 10 of the wounded in a shooting by a student at a vocational school in Crimea will be airlifted to hospitals in Russia.

An 18-year-old student went on a shooting rampage at the school on the Crimean Peninsula, which Russia annexed from Ukraine in 2014, killing 19 people and wounding more than 50 others before killing himself. Wednesday's attack in the city of Kerch was by far the worst school shooting by a student in Russia.

Health Minister Veronika Skvortsova told Russian news agencies on Thursday that authorities are preparing to airlift at least 10 people with severe injuries to top Russian hospitals for surgery. Dozens more remain hospitalized in Kerch.
