Rouhani says country will sign deal only if punitive measures are lifted 'on the same day'

Iran will only sign a final nuclear accord with six world powers if all sanctions imposed because of its disputed atomic work are lifted on the same day, President Hassan Rouhani said in a televised speech on Thursday.

Iran and the powers reached a tentative agreement last week in Lausanne, Switzerland, aimed at restricting Teheran's nuclear program in return for removing economic penalties.
