The main task for today is to clear the water park area of the rubble. Rescuers worked all night, said the mayor. The builders are to complete the work today.
Luzhkov also said that part of the roof was hanging on the columns, which could cause another collapse.
When asked about the reasons for the tragedy, the mayor said it was premature to make any conclusions. According to Luzhkov, a special commission has been set up by the Moscow government and the State Construction Committee to make final conclusions on the reasons of the accident.
