AKIPRESS.COM - Russia is believed to be the source of an influx of weapons to the Taliban in Afghanistan, General John Nicholson, the commander of U.S. forces in Afghanistan, said in a press conference on Monday.

Secretary of Defense James Mattis, who appeared with Nicholson at Resolute Support headquarters, said the U.S. would have to "confront Russia" over "denying the sovereignty of other countries," including Afghanistan, ABC News reported.

"For example, any weapons being funneled here from a foreign country would be a violation of international law," said Mattis.

Asked if he would refute claims that Russia is providing weapons to the Taliban, Nicholson answered definitively.

"Oh no, I’m not refuting that," the general said.

Nicholson said the U.S. has continued to receive reports of Russian assistance to the Taliban.
