Independent on Sunday: Iran's President has issued a defiant warning to his country's "enemies" as Tehran ignored a deadline from world powers hoping to curb Iranian nuclear ambitions.

Reuters: Iran said on Saturday it would not back down "one iota" in its nuclear row with major powers, voicing defiance on the day of an informal deadline set by the West over Tehran's disputed atomic ambitions.

AP: Germany's foreign minister urged Iran to stop playing for time and deliver a "clear answer" to initiatives offered by six world powers in the standoff over Tehran's nuclear ambitions, according to an interview released Saturday.

Reuters: The clock is ticking for Iran to respond to an offer by major powers on its nuclear programme, but European diplomats say they are ready to wait a few more days beyond Saturday's informal deadline for an answer.

AFP: The United States on Friday reaffirmed a weekend deadline for Iran to answer an international offer to freeze its nuclear drive and warned of new sanctions if it rejects the package.

Reuters: Iran's president said on Friday the Islamic Republic would "stand against" its enemies with its "power", speaking just before a deadline set by Western officials in a dispute over Tehran's nuclear ambitions.

AP: Iran sought but failed to win support from nonaligned nations this week for lifting U.N. sanctions and kicking the U.N. Security Council out of the dispute over its nuclear program, U.S. officials said Friday.
