U.S. scientists raise doubts about anti-missile shield

American scientists have expressed doubts to U.S. Congress about the effectiveness of the planned anti-missile defence shield in Europe. They say the system would not be able to provide the U.S. and Europe with protection against Iran and North Korea.

A senior advisor at the Centre for Defence Information says the system in its current form is not yet proven in real-life situations.

Russia insists that the possible construction of AMD bases in Poland and the Czech Republic is a threat to its national security.

During the latest negotiations, the U.S. acknowledged Russian concerns and offered to be fully transparent about its plans. Negotiations are set to continue.
