"We need a political solution, a solution of this kind requires cessation of any military activity and beginning of a dialogue. Without doubt, we are following Russia's effort in helping both sides of the conflict," Brahimi said in an interview with RT and RIA Novosti.
According to Brahimi, it is clear the conflict cannot be solved militarily but that, "there are many sides who do everything for the development of the military scenario."
Syria has been in a civil war since 2011, as the government battles many militant groups.
The warring parties have met twice over the last three years at UN-backed Geneva conferences but failed to stop the violence.
Moscow has hosted two rounds of intra-Syrian talks. At the second round of consultations held April 6-9, the sides agreed on a 10-point agenda defining a negotiating framework.
The latest round of intra-Syria talks is due to start on May 4 in Geneva.
