Bomber attacks Bagram Air Base during Cheney visit

But not to worry, Cheney will still not be able to admit that there's a problem.

The attack occurred inside one of the security gates surrounding the heavily guarded base some 60 kilometres (37 miles) north of the capital Kabul.

"It was a suicide bombing. It took place between the main gate and the gate guarded by American soldiers," said Bagram district governor Kabir Ahmad.

"We don't have an exact figure but it's said that two have been killed and about 18 wounded," he said. A local police officer said the area had been sealed off by US troops.

It's hard to say what it would take for this crowd to admit their failures but for most, this attack would be a red flag. Let's see what Cheney's office has to say later on today.
