"We have decided to call for a four-day night blockade as a move to intensify our stir to protest against the state government's failure to implement the ILP in the state," Khasi Student Union (KSU) vice president Fredrick Kharmawphlang told PTI here.
The 7 pm to 5 am night road-blockade would be effective in all the 11 districts of Meghalaya, he said.
The decision was taken at a meeting of the 10 pressure groups a day after the statewide office picketing, which has affected functioning of government machineries, concluded on Saturday last.
He said, "We will announce our next course of action after September 13. We Will fight till our demand is met."
Appreciating the public for their support, he appealed to all the people, including government employees to continue to extend their support and cooperation on the issue.
The Khun Hynniewtrep National Awakening Movement has also called for a one day sit in demonstration on tomorrow to express opposition and to create awareness on the need to implement the ILP system in the state.
