In separate interviews on Wednesday, the chairmen of these councils also said that crops and livestock worth millions of naira had been washed away by the flood.
Three persons died in Lau and two in Karim-Lamido councils respectively.
Alhaji Tukura Bashir, Chairman of Gassol local government area, noted that such disaster had not been witnessed in the area in the past five decades.
Bashir said that villagers on the banks of the River Benue, the major cause of the devastation, had seen many corpses floating on the river.
Meanwhile, the Chairmen of Lau, Mr Anthony Danburam and his Karim-Lamido counterpart, Mr Idi Mali, both confirmed to NAN that many people were also displaced.
NAN reports that in all the affected councils, thousands of people were displaced and farmlands submerged.
The development raised fears of food shortages due to the loss of crops such as rice, maize and beans, among others to floods across Taraba in the past one month.
All the council chairmen and farmers have called for urgent intervention by the National Emergency Management Agency (NEMA), the state government and well-meaning individuals to provide succour to the people.
They said the call for assistance had become necessary because the magnitude of the devastation was beyond the capacity of the councils. (NAN)
