The talks in Islamabad marked the first direct meeting between the US and Iran in over a decade, and the highest-level consultations between the two countries since the 1979 Iranian Islamic Revolution. The Iranian delegation arrived in Islamabad early on the 11th, dressed entirely in black to commemorate Supreme Leader Khamenei and other victims of the war. The Iranian government stated that the delegation also carried shoes and schoolbags belonging to students who were killed in a US bombing of a school adjacent to military facilities. Another Pakistani source, commenting on the first round of talks, said, "Emotions fluctuated between the two sides; the atmosphere was sometimes tense, sometimes relaxed." (Reference News)
