Purbo Banglar Communist Party
The Purbo Banglar Communist Party (East Bengal Communist Party) or PBCP is an outlawed Communist Party in Bangladesh. The PBCP formed in 1968 following a split in the Bangladesh Communist Party. It is mainly active in the areas of Khulna and Jessore in the South West of Bangladesh near the border of the Indian state of West Bengal where CPI-Maoist Naxalite insurgents have been active in an ongoing Civil War against the Indian state. The PBCP suffers from violent rivalry both internally and externally with different Party factions and rival splinter groups. The PBCP was criticized by Siraj Sikder, the founder of the Purbo Bangla Sarbohara Party, as being a neo-revisionist and a party that is "left in form but right in essence". History 
During the Bangladesh Liberation War in 1971, it was led by Abdul Matin-Alauddin Ahmed and failed to make a significant impact on the war. Tipu Biswas was also a major leader of the party. After the independence of Bangladesh the party broke into multiple fractions and followed the ideology of Charu Majumdar of India. The party started an insurgency against the government of Bangladesh. In January 2004, the party killed two journalists in Khulna, Manik Chandra Saha and Humayun Kabir Balu. Bangladesh police detained two activists of the party from Bagmara Upazila on 10 April 2007. On 28 January 2014, police kill PBCP leader Islam Sabuj in a gunfight in Phultala upazila. On 24 December 2015, three leaders of the party in Tangail were killed in a shootout with Rapid Action Battalion-12. Seven hundred activists of Purbo Banglar Communist Party, New Biplobi Communist Party, and Purbo Banglar Sorbohara Party surrendered in a ceremony to the Minister of Home Affairs, Asaduzzman Khan, in April 2019.
