Iran buries Khamenei as new fighting tests ceasefire

Iran has buried its slain Supreme Leader, Ayatollah Ali Khamenei, at the country's holiest shrine in Mashhad. Khamenei was killed months earlier in a US strike on the first day of the war between Iran and the United States. His burial comes as renewed fighting between Iran and the US threatens a shaky ceasefire deal. Both countries are reportedly exploring diplomatic channels amid the escalating violence.
