Iranian President Mahmoud Ahmadinejad announced Sunday that Iran will not halt its nuclear program, despite new sanctions adopted by the U.N. Security Council. It also announced that it is partially suspending cooperation with the U.N. nuclear watchdog agency, citing the "illegal and bullying" U.N. Security Council sanctions imposed on the country for its refusal to stop enriching uranium.
A different crisis is brewing between Iran and Great Britain over the 15 British sailors and Royal Marines captured by Iran.
