Reviving decades-old cries of "Death to America," Iran on Monday marked the 40th anniversary of the 1979 student takeover of the U.S. Embassy in Tehran and the 444-day hostage crisis that followed as tensions remain high over the country’s collapsing nuclear deal with world powers. The Persian on top of the placard is a quotation of the Supreme Leader Ayatollah Ali Khamenei which reads: "U.S. is on the verge of annihilation." (AP Photo/Vahid Salemi)
