Iran has used a conference on stopping terrorism to accuse the West of being the main sponsor of political violence against civilians.
President Mahmud Ahmadinejad told delegates who included the leaders of Iraq, Afghanistan and Pakistan that Washington, Israel and Europe support "individuals and groups responsible for [terrorist] incidents."
Iran's Supreme Leader Ayatollah Ali Khamenei, in a letter read out loud to the conference, also said Washington had indulged in "terrorist behavior and financial and military support to organized terrorists" in the Middle East.
The two-day international summit on terrorism, which began on June 25 at the Foreign Ministry in Tehran, is also being attended by the presidents of Sudan and Tajikistan as well deputy presidents and prime ministers from several other countries.
Tehran argues that the most effective way to fight terrorism is to allow regional countries to take care of security and force foreign troops to leave the region.
