Iran began a procession Monday through its capital, Tehran, for the funeral of the late Supreme Leader Ayatollah Ali Khamenei.

Khamenei's flag-draped coffin, and those of his family killed Feb. 28 in an airstrike at the start of the war launched by Israel and the United States, sat on board a truck. Authorities decorated the truck's side to resemble the ornamental grating that surrounds the shrine of an imam.
