CCTV footage appears to show a woman walking with a box outside the St Petersburg cafe where a Russian military blogger was killed in an explosion.

Vladlen Tatarsky, a vocal supporter of Russia’s invasion of Ukraine, died in a blast at Street Food Bar No 1 on Sunday evening (2 April).

Russian outlet Interfax named Daria Trepova, 26, as a suspect who was detained on suspicion of Tatarsky’s murder.

Mr Tatarsky was a guest speaker at a political event at the cafe when the bomb exploded.
