(CNN) -- The death toll rose to seven Thursday from a bombing outside a planned performance by a dance company in Russia, officials said.
About forty people were injured in the Wednesday bombing. The bomb went off outside a community center in the southwestern Russian city of Stavropol, according to the Investigation Committee of the Russian Prosecutor's Office, which called the explosion "an act of terror".
The blast happened about 6.45 p.m. (10:45 a.m. ET), 15 minutes before the Chechen dance company Vainakh was scheduled to perform, the committee said.
One of the dead included a pre-teen girl, according to state-run news agency RIA-Novosti.
