Major airlines from around the world on Friday began rerouting their flights to avoid areas around the Strait of Hormuz following Iran’s shooting down of a U.S. military surveillance drone there, as America warned commercial airliners could be mistakenly attacked. Hajizadeh said on Friday, Iran had warned a U.S. military surveillance drone several times before launching a missile at it. (Meghdad Madadi/Tasnim News Agency/via AP)
