Thousands of civilians are reported to be fleeing their homes in Pakistan's Swat valley where a peace deal with the Taleban looks increasingly fragile.
More than 40,000 people have so far fled from clashes between the army and militants in Swat, officials say.
Fighting erupted on Tuesday night in Mingora, Swat's main town, where the Taleban defied a curfew, they add.
Pakistan's army says it killed more than 60 militants in Swat and neighbouring Buner on Wednesday.
Bedraggled men, women and children are fleeing the area to settle in camps set up by the government with UN help.
