Rescuers work amid debris of a destroyed dormitory building of the Starobilsk College of Luhansk Pedagogical University following an overnight attack.

Russia used a new hypersonic ballistic missile in one of its biggest bombardments of the Kyiv region since the war began, an attack that left at least four people dead.

The United States classifies the Oreshnik, which can carry multiple conventional or nuclear warheads, as an intermediate-range missile. Its speed and trajectory make it almost unstoppable by the air defence systems available to Ukraine. It is only the third time Russia has used the missile.
