Britain's PM calls on Iran to halt nuclear program

In a formal address to Congress on Wednesday, Brown says the U.S. and Britain are ready for Iran to rejoin the world community after it stops threatening peace. He says the nations' leaders will work tirelessley with the international community to reduce the threat of nuclear proliferation.

Iran denies it wants to build a bomb. It asserts its program is intended to provide the country with the ability to generate electricity from nuclear reactors.

A top Iranian military commander on Wednesday said the Islamic Republic's missiles can reach Israeli nuclear sites, amid persistent speculation that Israel could target facilities involved in Iran's atomic work.

"All the nuclear facilities in different parts of the land under the occupation of the Zionist regime are in the reach of Iran's missile defenses," the commander-in-chief of the Revolutionary Guards, Mohammad Ali Jafari, said according to Iran's ISNA news agency.

Iranian officials often refer to Israel's government, which Tehran does not recognize, as the "Zionist regime."
