Each day we take a look at the main stadia and ticketing news from the 2016 Olympic Games.

Several people were injured when a television camera that had been suspended around 20 metres in the air fell to the ground at the Olympic Park on Monday. Nobody was seriously hurt.

Organisers are waiting to assess the damage after a forest fire broke out by the Deodoro shooting venue and neared the mountain bike centre on Monday. The UCI, cycling’s global governing body, denied reports that the latter venue had to be evacuated during the fire.

Competitors in the swimming marathon insisted there was nothing wrong with the water quality of Guanabara Bay. The venue has also staged sailing events during the Games and has come in for criticism.

So-called ‘ready-to-play’ turf has been fitted at the Maracanã stadium ahead of the football semi-finals, which get underway later today (Tuesday). The stadium was transformed for the opening ceremony on August 5 and will host the closing ceremony on Sunday.

An Iranian fan and activist was permitted to enter the volleyball venue on Monday with a banner that read, ‘Let Iranian women enter their stadiums’. Darya Safai had previously been told that she would not be allowed to display the message due to Olympic policy.
