"We are all Indians and we should stay together. We should solve our problems mutually," Gandhi told reporters after visiting the Basugaon high school relief camp in Chirang district.
Interacting with refugees at Basugaon and several other camps in the troubled area, the AICC leader assured them help from both the Centre and the state.
"We are there with you," said Gandhi after he diverted from his original schedule of visiting only four relief camps.
Breaking the security cordon, Gandhi spoke with the refugees and heard their problems.
He was accompanied by Chief Minister Tarun Gogoi and APCC president Bhubaneswar Kalita.
Heavy rain and poor visibility prevented Gandhi from boarding a IAF helicopter from Salakati to the Lokapriya Gopinath Bordoloi airport.
Instead he went by road before flying back to Delhi.
