The threats lay bare a complicated dynamic between the Taliban, Al Qaeda and the Haqqani network, and their bitter rival, ISIS-K, in what analysts say portends a bloody struggle involving thousands of foreign fighters on both sides.
A United Nations report in June concluded that 8,000 to 10,000 fighters from Central Asia, the North Caucasus region of Russia, Pakistan and the Xinjiang region in western China have poured into Afghanistan in recent months. Most are associated with the Taliban or Al Qaeda, the report said, but others are allied with ISIS-K.
“Afghanistan has now become the Las Vegas of the terrorists, of the radicals and of the extremists,” said Ali Mohammad Ali, a former Afghan security official. “People all over the world, radicals and extremists, are chanting, celebrating the Taliban victory. This is paving the way for other extremists to come to Afghanistan.”
