Pentagon demands Wikileaks return Afghanistan documents

The Pentagon has demanded that Wikileaks remove a trove of secret documents on the Afghanistan war from its website and cancel plans to publish anything more it holds.

But a Pentagon spokesman acknowledged the already-leaked documents' viral spread across the internet made it unlikely they could ever be quashed.

"We are asking them to do the right thing," BBC News quoted spokesman Geoff Morrell as saying.

The US military documents released last month detail civilian deaths, friendly-fire episodes and other ground-level incidents.

They include allegations the Pakistani intelligence service has backed the Taliban insurgents' fight against the US-led coalition and the Afghan government, and indicate Taliban fighters have acquired surface-to-air missiles.
