The Wall Street Journal reports:
Iran said it would end diplomatic efforts to resolve the crisis over its nuclear program after the Security Council on Wednesday imposed a fourth round of sanctions to persuade Tehran to stop enriching uranium. The resolution passed with 12 votes in favor and two against — Brazil and Turkey. Lebanon abstained. The new measures include an arms embargo on several types of heavy conventional weapons, but they largely build on existing sanctions, some which were imposed as early as 2006.
