While GJM leader Amar Singh Rai termed the situation in the hills as "very very volatile" and claimed a separate state of Gorkhaland is the biggest priority for them and rebuffed any possibility of discussions with the Bengal government.
The Gorkha activists on Sunday blocked roads and staged demonstrations at many places in the Dooars in support of the GJM's call for 12-hour strike in the region as the agitation in the hills spilled onto the plains.
The violence in Darjeeling took an ugly turn in Singmari after a massive rally towards Patlebas was halted by the security forces on Saturday afternoon.
West Bengal Chief Minister Mamata Banerjee also backed the police claims and accused the GJM of having links with terrorists and insurgent groups in the northeast.
The GJM announced an indefinite general strike from Monday in the hills encompassing Darjeeling and Kalimpong districts and the Dooars (foothills of the Himalayas covering stretches of Jalpaiguri and Alipurduar district) to oppose the government's purported decision to make study of Bengali language compulsory in state-run schools and to press for a separate state of Gorkhaland.
