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.
Officials say that more than 40,000 people have so far fled from clashes between the army and militants in Swat.
The renewed tension in Swat comes ahead of a meeting between US President Barack Obama, President Karzai of Afghanistan and President Zardari of Pakistan, in Washington.
Barbara Plett reports from Islamabad.
