China said on Monday it was "deeply concerned" after Iranian President Ebrahim Raisi's helicopter went missing in what Tehran's state media described as an accident, and pledged to help the rescue operation. "The Chinese side is deeply concerned about the hard landing of the helicopter in which President Raisi was travelling, and we wish President Raisi and the crew on board safe and sound," state broadcaster CCTV quoted Beijing's foreign ministry as saying.
