The killing of Igor Kirillov is a wake-up call for the Russian capital, writes Steve Rosenberg.

Attacks on Russian figures have become more brazen as Ukrainian special services penetrate security in Moscow.

Ukrainian sources tell the BBC the country's security service was behind the killings.

Steven Rosenberg reports from where a Russian general died in a blast at a residential block.

Romania's election was cancelled after thousands of TikTok accounts were activated backing a little-known candidate.

Footage from the scene shows a blast targeting the Russian general as he left a Moscow apartment block.

Some observers say we should not be too quick to dismiss Pyongyang's military capabilities.

Kirillov, who has been killed in Moscow, was accused by the West of overseeing the use of chemical weapons on the battlefield in Ukraine.
