KABUL:Head of US forces in Afghanistan Gen John Nicholson claimed Russia is supporting and even supplying arms to the Taliban and that  he’d seen “destabilising activity by the Russians.”

He said Russian weapons were smuggled across the Tajik border to the Taliban, but could not say in what quantity. He said Russia has denied such US allegations in the past, citing a lack of evidence. But the new claims come at a sensitive time in Russia’s ties with Nato powers.

Britain and Russia are locked in a dispute over claims that Russia was behind an attack on a former Russian spy and his daughter on UK soil using a deadly nerve agent.

Meanwhile a US Congressional Intelligence Committee has just published a report concluding that Russian provocateurs meddled in the 2016 election.

“We see a narrative that’s being used that grossly exaggerates the number of Isis [Islamic State group] fighters here,” Gen Nicholson told BBC News.

“This narrative then is used as a justification for the Russians to legitimise the actions of Taliban and provide some degree of support to the Taliban.”

“We’ve had stories written by the Taliban that have appeared in the media about financial support provided by the enemy. We’ve had weapons brought to this headquarters and given to us by Afghan leaders and said, this was given by the Russians to the Taliban,” he continued. “We know that the Russians are involved.”

Much of Gen Nicholson’s career has been spent in the conflict in Afghanistan. He narrowly escaped death when his office in the Pentagon was destroyed by one of the 9/11 planes and the US campaign in Afghanistan has shaped his career ever since.

He believes this direct Russian involvement with the Taliban is relatively new. He says Russia has conducted a series of exercises on the Afghan border with Tajikistan. “These are counter terrorism exercises,” says Gen Nicholson, “but we’ve seen the Russian patterns before: they bring in large amounts of equipment and then they leave some of it behind.”

The implication is that these weapons and other equipment are then smuggled across the border and supplied to the Taliban.
