Russian state media says that an Uzbek citizen accused of acting on behalf of Ukraine has been charged by Russian authorities with this week’s assassination of a senior Russian general and his assistant.

Russia's ballistic missile attack on Ukraine’s capital, Kyiv, killed at least one person; a Ukrainian attack on Russian border town killed six, officials say.

The killing of a senior Russian general in a bombing outside his apartment building in Moscow was the boldest assassination yet of a top military officer and it again brought the war in Ukraine to the streets of the capital.

The head of Russia's chemical and biological forces, Lt. General Igor Kirillov, was killed in a Moscow bomb blast claimed by Ukraine.

A 29-year-old Uzbekistan citizen has been detained over the death of Kirillov and his assistant, state media says.

Russia's security service said Wednesday it detained a citizen from Uzbekistan in the bombing that killed a senior general as he left his southeastern Moscow apartment -- a bold assassination that was claimed by Ukraine's security service.
