Secretary of State John Kerry plans to meet his Iranian counterpart this week for the highest-level face-to-face between Washington and Tehran in six years.
The meeting with Foreign Minister Javad Zarif and representatives of five other world powers — Russia, China, Britain, France and Germany — would come as newly elected Iranian President Hassan Rouhani visits the United Nations in New York. The talks would center on Iran's nuclear program.
As the host of the United Nations, the U.S. is supposed to let everyone come to the annual U.N. General Assembly, not just the people it likes.
But this year, the proposition is being put to the test. Sudan's president, Omar al-Bashir, was indicted three years ago by the International Criminal Court on genocide charges stemming from the mass killings in Sudan's western Darfur region.
Bashir has also applied for a visa to the U.N. meetings next week.
Secretary of State John Kerry says that tests have shown evidence of Syria's use of the chemical agent sarin in an attack on the opposition last month that the White House has blamed on the regime of President Bashar al-Assad.
"I can share with you today that blood and hair samples that have come to us through an appropriate chain of custody from East Damascus, from first responders, it has tested positive for signatures of sarin," Kerry told CNN on Sunday.
