Shillong: BSF Meghalaya Frontier inspector-general P.K. Dubey on Wednesday said fencing was necessary for the security of border residents.

"In areas where fencing has been completed, we have been able to put a more effective check on smuggling and militancy. It (fencing) will help in border surveillance," he said.

Informing that about 90km of unfenced areas remain in the Khasi and Jaintia Hills, Dubey said around Rs 110 crore has been deposited with the Meghalaya government for the purpose of acquiring land for fencing.
