The Bangladesh-India border is characterized by violence and is considered the deadliest border in the world. Some key reasons for the violence include illegal immigration from Bangladesh to India, cattle smuggling between the countries, and illegal arms trading across the porous border. Since 1971, over 1,200 Bangladeshi civilians and border guards have been injured or killed by firing from the Indian Border Security Force. Corruption within the Bangladeshi border guards has also contributed to ineffective control of border violence. The violence and killings have negatively impacted bilateral relations between Bangladesh and India.
