St Nedelya Church assault
The St Nedelya Church assault was a terrorist attack on St Nedelya Church in Sofia, Bulgaria. It was carried out on 16 April 1925, when a group of the Military Organisation of the Bulgarian Communist Party (BCP,) directed and supplied by the Soviet Military Intelligence (Soviet resident Boris Ivanov headed the operation, Vladimir Nesterovich smuggled the explosives,) blew up the church's roof during the funeral service of General Konstantin Georgiev, who had been killed in a previous communist assault on 14 April. 150 people, mainly from the country's political and military elite, were killed in the attack and around 500 bystander believers, who attended the liturgy, were injured.
