Tehran often accuses its arch enemies, Israel and the United States, of backing anti-Iran militant groups. State TV showed crowds gathered at the cemetery at night, chanting: "Death to Israel" and "Death to America". The United States was not involved in any way in the explosions and has no reason to believe Israel was, U.S. State Department spokesperson Matthew Miller told a regular news briefing. Iran's foreign ministry said in a statement that it will use all international means to identify and bring to justice those involved in the attacks and their supporters. Meanwhile, President Raisi cancelled a planned visit to Turkey on Thursday.
