The Indian Ministry of Home Affairs (MHA) has extended the ban on the National Socialist Council of Nagaland (Khaplang), also known as NSCN(K), for another five years, declaring it an unlawful association along with all its factions, wings, and front organizations. The ban, enforced under the Unlawful Activities (Prevention) Act (UAPA) of 1967, will take effect on September 28, 2025.

This decision reflects the Indian government's continued concerns regarding the group's activities, which are perceived as a threat to the country's sovereignty and integrity. The MHA stated that the NSCN(K) aims to create a sovereign Nagaland by seceding from the Indian Union and incorporating Naga-inhabited areas across the Indo-Myanmar region. The group has also aligned itself with other unlawful associations, including the ULFA(I), PREPAK, and PLA.

The government has accused the NSCN(K) of engaging in various criminal activities, such as kidnapping for ransom and extortion targeting businessmen, government officials, and civilians. The group is also alleged to possess illegal arms and ammunition and to have sought assistance from anti-India forces in other countries to procure arms and other support.

The NSCN(K) had previously entered into a ceasefire agreement with the Indian government, leading to the ban being lifted in 2001. However, the group later abrogated this ceasefire, resulting in renewed attacks and prompting the government to reinstate the ban. In 2015, the government moved to re-impose the ban on NSCN(K) following an ambush and killing of 18 soldiers in Manipur. The Ministry of Home Affairs cited multiple incidents to justify the ban, including the June 4 attack on an Army convoy and an attack on a convoy of Assam Rifles in May that resulted in the deaths of eight security personnel.

Intelligence agencies estimate that the NSCN(K) has a significant number of cadres and possesses sophisticated weaponry. The group is believed to have established camps in Myanmar to conduct secessionist activities, recruit members, and carry out terrorist attacks on Indian forces. The National Investigation Agency (NIA) has also declared rewards for the NSCN(K)'s military commander and chief for their involvement in planning attacks.
