**Russian General Killed in Moscow Blast**
A powerful explosion has killed Russian Lt Gen Igor Kirillov and his assistant in Moscow. Ukrainian sources have claimed responsibility for the attack.
**What Happened?**
The blast occurred on Tuesday morning outside a modern apartment building in south-east Moscow. The device, hidden in a parked scooter, was detonated as Lt Gen Kirillov and his assistant were leaving the building.
**Investigation Underway**
BBC Verify has been analyzing social media videos and images from the scene to build up a clearer picture of the blast. Experts at Janes and McKenzie Intelligence have suggested that the explosion was caused by an Improvised Explosive Device (IED), rather than a conventional munition.
**IED Suggested as Cause**
The experts say that the IED contained easily obtainable components, such as nails or metal fragments, which can cause significant damage. They also suggest that the attack demonstrated “a decent level of sophistication” and may have taken months of preparation.
**Details of the Blast**
Russian state media has said that the bomb used up to 300g of explosive material. This is equivalent to a significant amount of TNT, which can cause substantial damage.
**Eyewitness Accounts**
An eyewitness has shown Russian media images of debris from the explosion landing in his flat across the street from the site. BBC Verify is examining these images with weapons experts to establish whether they could have come from the device.
**Investigation Continues**
BBC Verify will continue to examine footage from the scene as it comes in and bring updates on this developing story.
