Turkeys foreign minister has urged the United States and Iran to avoid escalating tensions following the allegations that Iranian agents plotted to kill the Saudi ambassador to Washington. Ahmet Davutoglu said Friday he did not believe Iran would engage in such a plot but added that the United States insists it has evidence for it. Davutoglu was speaking at a joint news conference with his Iranian counterpart Ali Akbar Salehi who rejected the U.S. allegations as weak, baseless and empty.
