In the report on Saturday, the German news magazine "Spiegel" cited a senior Saudi government official as saying that Riyadh wanted to help Germany find those behind Islamist bomb and ax attacks in July that left 20 people injured and the two assailants dead, Deutsche Welle writes.
"We want to jointly do everything possible to clarify the backgrounds of the attacks," the official was quoted as saying.
Saudi authorities were already in contact with their German authorties, according to the magazine.
The "Spiegel" report said new findings had shown that up until shortly before their crimes, both attackers had been in close contact via a chat conversation with possible supporters of the jihadist group Daesh in Saudi Arabia.
Traces of the chats indicated that both men had been not only been influenced by the unknown Daesh backers, but had even received instructions on how to proceed, the report said.
