(CNN) -- The evacuation of thousands of Pakistani civilians has become a major challenge as military planes attacked suspected anti-government militant hideouts in North Waziristan. More than 60,000 people, many of them children, have fled for safer areas in Pakistan and Afghanistan, according to a United Nations-supported news network that reports on humanitarian efforts. The Integrated Regional Information Networks said Pakistani authorities haven't set up camps yet. But Pakistani officials said school buildings in the Bannu, Lakki Marwat, Tank, Karak and Hangu districts would be opened as shelters for people fleeing the conflict. Pakistan on Sunday launched a military operation in North Waziristan, a restive province near the border with Afghanistan,in an attempt to "finish off" militants in the area "once and for all," Defense Minister Khawaja Asif told CNN. The Pakistani Taliban is among the targets.
