Via NBC News:

Taliban leaders tuned into Monday night’s debate between Hillary Clinton and Donald Trump from a secret location in Afghanistan, a spokesman for the militant group told NBC News.

“We were very interested in watching,” said Zabihullah Mujahid.

The spokesman added that “Trump … [says] anything that comes to his tongue” and branded the Republican candidate as “non-serious.”

He said the militant group’s leadership had hoped that Afghanistan would feature more prominently in the discussion.
