MOSCOW, July 8 (RIA Novosti) - The report of a parliamentarian commission investigating the September 2004 Beslan school tragedy will be delivered in September, the speaker of the Russian parliament's lower chamber, the State Duma, said Friday.

Boris Gryzlov said a deputy speaker, Sergei Baburin, had asked when the report would be published because members of parliament had still not heard any results from the commission, which is chaired by Federation Council Vice Speaker Alexander Torshin, even though it had been conducting its investigation for months.

Yury Savelyev, a member of the investigation commission, said it was impossible to complete the report at the moment because new circumstances were constantly emerging. He said the commission would work throughout the summer and would make several trips to the region where the tragedy occurred.

As a result of the terrorist attack on the school in Beslan and the following rescue operation, 330 people were killed, including 172 children, and hundreds were hurt.
