Siliguri (West Bengal), July 15 - Life was paralysed in three hill subdivisions of West Bengal's Darjeeling district on day three of the Gorkha Janamukti Morcha (GJM)- sponsored indefinite shutdown, as the pro-Gorkhaland agitators Wednesday set two conditions for participating in the tripartite talks convened by the central government.

GJM activists took out a rally in Darjeeling town and squatted on three National Highways and other important roads which wore an empty look as vehicles did not ply.

Tea gardens remained shut, timber movement was stalled while road connectivity between Sikkim and rest of the country got snapped as the GJM workers blockaded the crucial National highway 31 A, the lifeline of the tiny Himalayan state.

Schools, colleges, shops and offices in the hill sub-divisions of Darjeeling, Kurseong and Kalimpong were closed, but the district court in Darjeeling town functioned.

A day after the central government convened the tripartite parleys in New Delhi Aug 24, GJM assistant general secretary Benoy Tanmang told reporters that the missive has reached his outfit.

However, he expressed anguish at the letter having no reference to Gorkhaland, a separate state demanded by the GJM and some other hill outfits in the northern part of the state.

He demanded that the tripartite discussion be held centring the Gorkhaland issue before the budget session of parliament came to an end.

'Secondly, the discussions must be at a political level.
