CNN reports:

Iran has been carrying out covert tests of missiles capable of delivering a nuclear payload, UK Foreign Secretary William Hague said Wednesday, in contravention of a U.N. resolution. It has also said it wants to enrich uranium to "levels far greater than is needed for peaceful nuclear energy," Hague said.... Hague's comments in the House of Commons come a day after Iranian news agencies reported that the country's military had successfully test-fired 14 missiles during military drills. Tehran also unveiled several ballistic missile silos Monday. Speaking in London, Hague said: "Iran has also been carrying out covert ballistic missile tests and rocket launches, including testing missiles capable of delivering a nuclear payload in contravention of U.N. resolution 1929, and it has announced that it intends to triple its capacity to produce 20% enriched uranium."
