Tehran warns us over 'collision course'
Iran's foreign minister said on Thursday that Tehran was ``prepared for the worst'' and warned the United States against putting itself on ``collision course'' with his country.
``I warn the US not to be after any mischief in the meeting of the Group 5+1 and to think on final settlement of Iran's nuclear case,'' Ayatollah Rafsanjani told large groups of Tehrani Friday prayers worshipers at Tehran University campus.
