 Iran is going to the polls to elect a new president following the death of Ibrahim Raisi in a helicopter crash last month. Iran's Supreme Leader Ayatollah Ali Khamenei has called for a maximum turnout. The Japanese embassy in Beijing has flown its flag at half-mast in honor of a Chinese woman, Hu Yuping, who was stabbed to death after confronting a knife-wielding man who attacked a Japanese woman and her child at the local bus stop.
