The journalist who helped break the story that detainees at the Abu Ghraib prison in Iraq were being tortured by their US jailers told an audience at a journalism conference last month that American soldiers are now executing prisoners in Afghanistan.

New Yorker journalist Seymour Hersh also revealed that the Bush Administration had developed advanced plans for a military strike on Iran.

At the Global Investigative Journalism Conference in Geneva, Hersh criticized President Barack Obama, and alleged that US forces are engaged in "battlefield executions."

"I’ll tell you right now, one of the great tragedies of my country is that Mr. Obama is looking the other way, because equally horrible things are happening to prisoners, to those we capture in Afghanistan," Hersh said. "They’re being executed on the battlefield. It’s unbelievable stuff going on there that doesn’t necessarily get reported. Things don’t change:

"What they’ve done in the field now is, they tell the troops, you have to make a determination within a day or two or so whether or not the prisoners you have, the detainees, are Taliban," Hersh added. "You must extract whatever tactical intelligence you can get, as opposed to strategic, long-range intelligence, immediately. And if you cannot conclude they’re Taliban, you must turn them free."
