The investigation into the collapse of the terminal roof at Charles de Gaulle airport in Paris may not finish until the end of the year.
A spokesperson for the airport operator said it could take four or five months, but experts would have a clearer idea in a few days.

The spokesperson said Terminal 2E, where the accident occurred, could reopen in a few weeks as only a 30 m section of the 700 m roof collapsed. The terminal was built in June last year.

Four people were killed in the accident, which occurred on 23 May. There has been speculation that the most likely cause of the accident was a fault in the construction process but it has also been alleged that the architect, Paul Andreu, ignored safety warnings. He has denied these claims.

Andreu was chief architect at Aéroports de Paris. Terminal 2E was the last building he designed before retiring from the group.
