2. Admiral Samuel Locklear "twice refused to deny" but 'an investigation is under way'

Admiral Samuel Locklear, the US commander in the Mediterranean briefing Pentagon reporters from aboard the USS Mount Whitney, twice refused to deny that a US helicopter sent to rescue downed airmen opened fire on Libyan villagers.

If the story was untrue, it seems likely that Locklear would have emphatically denied it and his failure to do so will lend credence to it. He said the rescue mission had been executed as he had expected it to be, given the circumstances. Asked if they had opened fire on villagers, he said he would restrict his comments to saying that an investigation was under way.

"twice refused to deny"

It's more like you put it, "or so they say".
