The night blockades will be enforced from tomorrow, from 7pm to 6am in the four districts of Khasi-Jaintia hills.
Slamming the delay in resolving the disputes, HNPF president R Ranee said the organisation is concerned about the plight of the people living along the border areas.
"The government has been casual in uplifting the condition of these people who have bore the brunt of the inter-state boundary and international border disputes," he said.
