• Killing of Russian general cements SBU's reputation for abrupt vengeance

A senior Russian general has died after an explosive device hidden in an electric scooter detonated outside an apartment building in Moscow, in an attack claimed by Ukraine that marks one of the boldest targeted assassinations of a senior military official since Russia's full-scale invasion of the country.

Lt Gen Igor Kirillov, the head of the military's chemical, biological and radiological weapons unit, was killed along with his assistant when the blast went off as the two men left a building in a residential area in south-east Moscow on Tuesday.
