National Thowheeth Jama'ath (NTJ) is a Sri Lankan extremist group that emerged in the early 2010s. It promotes a strict interpretation of Islam and has been linked to various acts of violence and radicalization within the country. The group gained international attention following the 2019 Easter Sunday bombings, which targeted churches and hotels, resulting in significant casualties. The NTJ is known for its anti-Western and anti-Christian sentiments, advocating for the establishment of an Islamic state in Sri Lanka. Authorities have since banned the organization, and investigations into its activities continue as part of broader efforts to combat extremism in the region.
