 The Military Intelligence, Covert Action Division (CAD) and army troops found many caves and tunnels in White Mountain range used by the foreign fighters before the military action took place.The Military Intelligence accounts maintained that the tunnels were led into Afghanistan, possible Tora Bora region.Though it is difficult to know how effective the cordon was on the first night of the military suspension but the military intelligence accounts did confirm that many high-value foreign fighters might have escaped through these tunnels and caves back to Afghanistan.
