Thousands flee Swat Valley violence

Thousands of people continue to stream out of Mingora, the main city in Swat valley, in north-west Pakistan. They want to escape fierce fighting between the army and Taleban insurgents, after the military lifted a curfew trapping people there.

Aid agencies and the government say up to 830,000 people have fled in the last month alone. Over the last year another half-million have been displaced by sporadic clashes between militants and government troops.

In Mingora, around 150,000 civilians are trapped, with gas, electricity and food increasingly scarce.
