What are the reasons for manipur blockade?

Senapati District in the state of Manipur is the place where this controversy has arisen. Actually this district is dominated by the Kukis and the Nagas. The Kukis in their demand for a separate district of Sadar Hill have caused this blockade. In retaliation to this blockade the Nagas have also imposed a parallel blockade in the state of Manipur. The Sadar Hill District Demand Committee is the main organisation behind the blockade representing the Kukis whereas the Nagas are represented by the United Naga Council which has imposed a parallel blockade, thus impairing the state of Manipur.
