Separatists say one killed amid violence in India's Darjeeling

Fresh violence erupted in Darjeeling Saturday (8) after a separatist group accused police of killing a supporter, prompting forces to fire tear gas as the Indian hill resort reels from weeks-long unrest.

Bouts of clashes and arson attacks have rattled the picturesque hill station for more than three weeks, causing schools and shops to shut down as thousands of mostly Indian tourists pack their bags and flee.

The Gorkha Janmukti Morcha (GJM) -- a movement that has long called for a separate state for ethnic Gorkhas in West Bengal -- accused police of shooting dead 31-year-old Tashi Bhutia late Friday (7).

"(He) was shot dead by police at Sonada on the outskirts of Darjeeling town when he was returning home from a medicine shop," GJM's general secretary Roshan Giri said.

But authorities, including West Bengal tourism minister Gautam Dev, have denied GJM's latest allegation, saying they were unaware of any death and that "police did not open fire".

The GJM has said it will parade Bhutia's body later on Saturday, according to the Press Trust of India.

The news of his death sparked anger among supporters who set ablaze and destroyed parts of a police station and train terminal as baton-wielding forces responded with tear gas and rubber pellets.

Chief minister Mamata Banerjee deployed the army again to quell heightened tensions, which she has described as a "deep-rooted conspiracy".

The hills are famous for Darjeeling tea, the production of which is jealously guarded. It is also famed for its "toy train" -- a 78-kilometre uphill ride from New Jalpaiguri.

Tension has been mounting in the region since the government announced it was making Bengali mandatory in state schools -- angering the state's Gorkha population, who speak Nepali.

Gorkhas have been agitating for decades for a new state of "Gorkhaland" within West Bengal, claiming Bengali-speaking outsiders have exploited their resources and imposed their culture and language.
