Iran's First Vice President Mohammad-Reza Rahimi said Monday that the issue of Afghanistan has no military solution, the official IRNA news agency reported.
Speaking to reporters prior to leaving Tehran for Istanbul to attend a conference on Afghanistan, he pointed out, "The occupying forces are now facing great problems as they have no comprehensive knowledge and information about Afghanistan and we are quite confident that they will leave the country regretfully."
Iran believes that the problems in Afghanistan can be solved merely through collective cooperation and contribution of countries in the region, Rahimi was quoted as saying.
Heading a delegation including several Iranian lawmakers, Rahimi left for Turkey on Monday evening.
Iran is also scheduled to participate in another conference on Afghanistan organized by the Shanghai Cooperation Organization ( SCO) in Moscow.
Iran's Foreign Minister Manouchehr Mottaki said last Thursday that Tehran would take part in a conference on Afghanistan in London next week providing that its viewpoints are fully taken into consideration.
He did not elaborate on the details of Iran's conditions, but Iran has already called on the NATO forces in Afghanistan to leave the country and let the Afghan people provide security with the help of regional states.
