Military action against Iran would be a “very serious mistake fraught with unpredictable consequences”, Russia’s foreign minister has warned, according to the BBC. Sergei Lavrov said diplomacy, not missile strikes, was the only way to solve the Iranian nuclear problem. His comments come after Israeli President Shimon Peres said an attack on Iran was becoming more likely. The UN’s atomic watchdog is expected to say this week that Iran is secretly developing a nuclear arms capability. Iran has always insisted that its nuclear programme is exclusively to generate power for civilian purposes.
