US forces are massing in eastern Afghanistan amid reports of an imminent drone missile offensive against fighters from the Haqqani Network, a Taliban faction that operates from safe havens in Pakistan's North Waziristan Agency, Pakistan army sources have confirmed.
The scale of the American build-up caused panic in north Waziristan, where tribal militias gathered in the capital Miranshah.
Local officials warned that Pakistan's armed forces would repel any incursion across the border by American forces, but military sources in Islamabad and Afghan officials suggested the build-up was co-ordinated.
Relations between Washington and Islamabad have deteriorated in recent months as American officials increased pressure on Pakistan to launch an offensive against the Haqqani Network. (©Daily Telegraph, London)
