The official stadium code of conduct previously stated: “For the avoidance of doubt, empty, transparent, reusable plastic bottles, up to (1 litre in) capacity, may be brought into the stadium.”
But seven days before the tournament kicked off on 11 June, Fifa reversed that policy, saying it will lower the risk of injury caused by fans throwing missiles.
Fans will be able to buy water in the stadium and Fifa has promised not to charge above usual venue prices.
However, heat experts criticised the ban, with one saying it would “clearly heighten the risk of heat-related health incidents”.
Fans were also prevented from taking bottles into stadiums at the last World Cup in Qatar.
