The Novye Aldi massacre was a massacre in which Russian federal forces summarily executed dozens of people in the Novye Aldi (Aldy) suburb of Grozny, the capital of Chechnya, in the course of a "mopping-up" (zachistka) operation conducted there on February 5, 2000, soon after the end of the battle for the city. As a result of a deadly rampage by the special police forces, between 60 and 82 local civilians were killed and at least six women were raped. Numerous houses were also burned and civilian property was stolen in an organized manner.The official investigation into the Aldi massacre established that the "sweep operation" there was conducted by the paramilitary police of OMON from the northern Russian city of Saint Petersburg (possibly also from the southern Ryazan Oblast). As of 2016 the Russian authorities had failed to hold anyone to account for the crime. The guilt of the Russian state in the Aldi murders and the denial of justice to the victims was formally established in two different judgements by the European Court of Human Rights in 2006–07.
