ZURICH/FRANKFURT, March 8 - The United States and Israel have broken international law with their attacks on Iran, Swiss Defence Minister Martin Pfister said in an interview published on Sunday, the latest European leader to raise concerns about the conflict.

Legal experts have said many countries will consider the attacks unjustified under the United Nations Charter, under which member countries must refrain from using force or the threat of force without U.N authorisation or unless acting in self-defence.
