Singh condemned all such incidents during a debate in the Lok Sabha on the violence in Kokrajhar, as also in Mumbai and other parts of the country against people from the North East.
"The growing sense of insecurity among the people from the North East fleeing different part of the country is something most reprehensible," he said.
Singh promised that he commits his government to work with all "like-minded" people to work together to bring the situation under control without any loss of time.
He emphasised that people from the North East had "as much right" as anybody else to study and work in any part of the country.
Singh urged the people to maintain unity and integrity of the country. The people are one and "we will do everything to provide them security," he said.
The Prime Minister said security was an obligation for his government and it will provide this to the best of its ability.
"We should send a clear message that we will do everything to provide security to people from North East living in various parts of the country," he said.
