On 28 December, at least three people were killed following a knife attack in the Chechen capital of Grozny. 

The leader of the Chechen Federal Republic Ramzan Kadyrov later confirmed the attack and published the identities of the attackers on his Telegram channel. One law enforcement officer was killed and another injured is in stable condition, while both attackers were shot dead by return fire, he said. According to Kadyrov, the attackers were two brothers named Khasan and Hussein who moved to Chechnya from their native republic of Ingushetia in 2012 and got jobs in a bakery. He stressed that the two suspects attempted to seize the weapons of patrol police officers who were serving in the centre of Grozny.

The Caucasian Knot reported that this was the fifth armed incident in Chechnya since the early 2020. Earlier, on 17 December, Chechen law enforcers shot and killed two people at a road-and-patrol service (known as DPS) checkpoint in Kurchaloi. According to the Chechen Ministry of Internal Affairs (MIA), law enforcers stopped a car to check the IDs of a driver and passengers. The attackers threw an improvised explosive device (IED) at the law enforcers and opened fire.

The day before, a special operation was conducted in the Achkhoi-Martan District of Chechnya. The Chechen leader Ramzan Kadyrov reported that suspected militant Kazbek Baidulaev had been killed during the special operation. When offered the chance to surrender, the suspect tried to throw a grenade and was killed by return fire. Meanwhile, the name of Kazbek Baidulaev had already been mentioned among the suspected militants killed after the special operation conducted in the Sernovodsky District on 11 October, together with suspected militant Rustam Borchashvili. Experts called to question the information concerning the special operations in Chechnya and noted that the law enforcement bodies should explain the mistake with the identification of Kazbek Baidulaev. 

On 13 October, two officers of the Russian National Guard were killed in an anti-terrorism operation in Grozny. The Chechen police surrounded the militants, who were holed up in a house in Grozny, and asked them to surrender. The militants opened fire in response, they reported. All four militants inside were killed in the ensuing shootout. Kadyrov stated after the operation that members of an illegal armed group had arrived in the region from abroad to Chechnya. The Russian Anti-Terrorism Committee said that 60 militants have been killed in the wider North Caucasus region since the beginning of 2020 and that 19 attacks were prevented.
