Sporadic incidents of violence and rallies were witnessed in the northern West Bengal hills on Monday as the pro-Gorkhaland supporters demanded that internet services be restored.

A group of Gorkha Janamukti Morcha (GJM) activists on Monday demonstrated outside the District Magistrate's office in Darjeeling demanding access to internet, which has been banned in the region since the last one month.

"The pro-Gorkhaland rallies are being held in Darjeeling, Kalimpong and various other places in the hills. We condemn these authoritarian steps (blocking internet) by the Bengal government," GJM General Secretary Roshan Giri told IANS.

The suspension of internet services, imposed on 18 June, has been extended till 25 July by the district administration.

Giri also condemned the "extremely rude behaviour" of Trinamool Congress legislator Paresh Pal, who lashed out at GJM MLAs during the presidential polls in the state assembly.
