Hundreds of Afghans have tried to rush the border
As thousands of desperate Afghan refugees gather at the Pakistani border at Chaman, near Quetta, there is increasing pressure on the Pakistani authorities to open up the crossings.
"People with identity papers please form an orderly queue," screamed a guard in the control tower at the crossing, in south-west Pakistan.
At least, that is the official line. The UN High Commissioner for Refugees says most of the people who make it across no-man's-land have paid bribes to the border guards or have fake Pakistani identity papers.
This would explain why there were so few refugees crossing during the two hours we were watching.
Two men and two children did come across on stretchers after apparently being beaten up by the Pakistani guards, as hundreds of Afghans tried to rush the border.
Changed situation
The situation has changed considerably since we first visited Chaman just under a week ago. Then, it had been relatively quiet, with more cameramen than refugees.
Today the number of police had doubled, and faced with the massed ranks of Afghans just 50m away they were understandably nervous.
"Don't let them see you or they will shoot," said one of the local commanders as I pointed a small video camera at the border.
I hid behind the armed guards as I watched the front line. But there seemed little evidence that there were any armed Taleban guards on the other side - only desperate people fleeing from the Taleban oppression and the American bombs.
Those refugees that did make it across were virtually all from Kandahar, the Taleban stronghold just 200km away on the other side of the border.
Desperate in Kandahar
One turned out to be a doctor, who tried to save the life of the son of the Taleban leader, Mullah Omar.
Dr Abdul Barri said he had fought for four hours to save the boy's life, but the 10-year-old had died after losing too much blood and because there was not enough medicine in the hospital.
In fact, Dr Barri said there were only five days' medical supplies left in the city.
The situation seems to have become increasingly desperate in Kandahar, forcing most of its citizens to leave.
But the Pakistani Government has given no indication that it will open the border. Indeed, the home secretary of the state - who was also at the border today - said he was concentrating all his efforts on bringing food and shelter across the border to help the Afghans - on the other side.
