NDRF Director General OP Singh told PTI that while five teams are being airlifted for immediate deployment from its base in Odisha to Uttar Pradesh, the rest five are being picked by choppers from Bathinda in Punjab and will be sent to Bihar.
"These fresh teams will be launched into operation by early tomorrow," the DG said, adding they would be equipped with boats and essential items like medicines.
Mr Singh said the teams will be in addition to the 56 such contingents which are undertaking flood combat operations in these two states, besides Rajasthan, Madhya Pradesh and Uttarakhand.
The DG also briefed Union Home Minister Rajnath Singh with full updates of the flood situation in these states late in the night.
In order to launch massive operations in the two worst-affected states of Bihar and Uttar Pradesh, the NDRF has created on-ground control rooms in these two states and deputed two senior Deputy Inspectors General (DIGs) S S Guleria (Patna) and R K Rana (Varanasi) to take control of the situation.
