British Prime Minister David Cameron has said the West should "ratchet up" pressure on Iran because "all the evidence points in the same direction -- that Iran is intent on developing nuclear weapons."
Cameron's comments echo an earlier statement by U.S. Secretary of State Hillary Rodham Clinton, who earlier in the day called a Turkey- and Brazil-brokered fuel-exchange plan for Iran a "transparent ploy
" by Tehran to avoid new UN Security Council sanctions over its disputed nuclear program.
The fuel-exchange agreement would send Iranian uranium to Turkey for development in exchange for fuel rods needed by Tehran. A day after the agreement was announced last week, the United States released a draft resolution for a fourth round of UN sanctions on Iran.
Iran insists that its nuclear program is peaceful, but Western countries fear it is secretly developing nuclear weapons.
