About 3,000 villagers were rescued and shifted to relief camps on Sunday, said defence PRO Lt Col S Newton.Water from the Brahmaputra overflowed into KNP – crossing six feet in many places — forcing animals to flee in search of shelter to the neighbouring Karbi Anglong district. “We will be able to ascertain the number of animal deaths only after the water recedes,” said Kaziranga divisional forest officer Rohini Ballav Saikia, adding that 148 out of 188 anti-poaching camps have been submerged.Four rhino calves have been rescued so far, Saikia said.Rail and road connectivity has been snapped in most places.
