The Kremlin is unable to say when the report on the A321 passenger jet crash that was blown up over Egypt’s Sinai Peninsula on October 13 will be published because it depends on the Russian and Egyptian investigators, Kremlin spokesman Dmitry Peskov said Wednesday.

Peskov said that he only knows “what was told to the president by the head of the [Federal Security Service] that this was a terrorist act.”

A Russian Airbus A321 crashed en route from Egypt’s resort city of Sharm el-Sheikh to St. Petersburg on October 31, leaving no survivors. The Russian Security Service (FSB) confirmed Tuesday that the detonation of a home-made explosive device was the cause of the crash.

“You have to understand that these are investigative bodies. We have our investigation, and Egypt has theirs, so we in the Kremlin cannot say anything on when the investigation will be published,” Peskov told journalists.
