Shillong, Nov. 26: Concerned over the activities of NSCN (I-M) and NDFB members, especially their help to local militant outfits, the Meghalaya government has decided to take up the matter with the governments of Nagaland and Assam as well as the Centre to ensure that the two outfits adhere to the ceasefire ground rules.

Assam is likely to recommend to the Centre a review of the ceasefire with the NDFB when the time for its extension comes up in December.

Meghalaya police are worried over the presence of NSCN (I-M) militants in East Garo Hills and West Khasi Hills districts as they are allegedly lending support to the Garo Hills-based Liberation of Achik Elite Force (LAEF) in its extortion activities.

At a recent meeting of the deputy commissioners and superintendents of police, chief secretary Ranjan Chatterjee asked the police officers to keep vigil to check the illegal activities of new militant groups like Atong Liberation Army in South Garo Hills and Achik National Security Defence in West Khasi Hills.

According to Meghalaya police, the two militant groups under the patronage of the NSCN (I-M) are carrying out extortion in the coal belts of South Garo Hills and West Khasi Hills districts.

The police also suspect a possible tie-up of the NDFB with Khasi outfit Hynniewtrep National Liberation Council (HNLC) and the LAEF which, according to police, is a cause of concern in the context of the overall security of the state.
