The intelligence reports come at a time when five separatist guerrilla groups in the northeast called a 17-hour general strike to boycott Independence Day.

The militant groups that called for a boycott of the Independence Day celebrations include the outlawed ULFA, the National Democratic Front of Bodoland (NDFB), the Kamatapur Liberation Organisation (KLO), fighting for a separate homeland comprising parts of Assam and West Bengal, the Manipur People's Liberation Front (MPLF), an umbrella group of several Manipuri rebel groups, and the Tripura People's Democratic Front (TPDF).

These groups are active in Assam, Manipur and Tripura.

As part of the boycott call Aug 15, the militant groups have called for a general strike from 1 a.m. to 6.30 p.m.

Militant groups in the northeast have for years boycotted national events to protest New Delhi's rule over the region.
