(Bloomberg) -- A deadly explosion at a Crimean school may have been a terror attack, President Vladimir Putin’s spokesman said Wednesday.

The possibility of terrorism “is being considered,” Dmitry Peskov told reporters on a conference call.

A blast caused by an unidentified explosive device killed at least 10 and wounded more than 50 in the city of Kerch, near the eastern end of the peninsula that Russia annexed from Ukraine in 2014, Russia’s National Anti-Terrorism Committee said.

Authorities opened a criminal probe and Putin ordered the Federal Security Service to investigate the explosion.

Russia has suffered a number of deadly terror attacks in recent years, as well as shootings by students at schools.
