A large number of tribesmen have started migrating from Saidgi, Bangi Dar in North Waziristan and other areas besides villages in the agency headquarters of Miramshah.
However, Political Agent Siraj Ahmad Khan told journalists that he had directed administration officials to tell the tribesmen not to leave the agency as there was no fear of an operation.
"A military operation is not imminent and there is no need for the tribesmen to flee," Siraj claimed.
However, local tribesmen told The Express Tribune daily that nearly 50,000 tribesmen have fled the agency since last month.
