He said that about 38 thousand people took part in the rallies on August 29 in Berlin.
At the same time, as a result of clashes between the police and a group of "right-wing extremists" who threw stones and bottles at police officers near the Russian embassy, seven police officers were injured, and about 200 people were detained.
"There is no immediate threat to the embassy so far," RIA Novosti quoted him as saying.
More than 300 people were detained during the whole day.
Earlier, the Berlin police reported dozens of detainees at the August 29 protest.
