Pakistan's government has started to return home some of the two million people displaced by conflict in the Swat Valley.
The first convoy of buses carrying people from temporary camps began its journey on Monday.
The army reopened roads into the troubled district after an offensive to drive out Taliban militants there.
Some of the displaced have already returned. Correspondents for the BBC say they are likely to rely on aid for many months. Power and water supplies have been shattered and reconstruction is expected to take many months.
The United Nations has stressed that the return, which will begin with people living in temporary camps, must be voluntary. Once people have been moved from the camps, the army will begin returning people who have been living in schools and other places since they fled the fighting.
Reports from that district say that there has been no fighting for nearly three weeks, despite frequent curfews and house searches by the army.
