Iranian President Mahmoud Ahmadinejad has said the proposed US missile defense shield in central Europe would pose a threat to Asia.

At a summit of the Shanghai Cooperation Organization (SCO) in Bishkek, the capital of Kyrgyzstan, Ahmadinejad said such a plan goes beyond threatening one country and it is a source of concern for most of the continent.

Washington is planning to station a radar station in the Czech Republic and interceptor missiles in Poland.

Ahmadinejad added the six SCO member states, including China, are among those countries who are threatened by the US plan.

He also criticized the US military attack on Iraq, which has destabilized the entire region.

Iran has observer status in the SCO, which groups China, Kazakhstan, Kyrgyzstan, Russia, Tajikistan and Uzbekistan.
