"We heard from everyone we met in the opposition, and everyone [else] we met that, if the government stops using violence, 'We will respond to this directly'," Brahimi said from Beirut today.
"The Syrian people are burying hundreds of people each day, so if they bury fewer people during the days of the holiday, this could be the start of Syria's return from the dangerous situation that it has slipped and is continuing to slip toward."
Brahimi also warned regional leaders today that the 19-month conflict could not be contained within Syria's borders for much longer. Syrian Army shelling has already landed in both Lebanese and Turkish territory multiple times, Agence France-Presse reports.
"This crisis cannot remain confined within Syrian territory," he told reporters. "Either it is solved, or it gets worse... and sets [the region] ablaze."
With support from Iran and Turkey secured, the next obstacle facing Brahimi is the Syrian opposition's lack of a unified leadership. The Syrian government has cited this as a key reason it has been unwilling to reach any previous agreement with the rebels, saying that even if one representative of the rebels signs an agreement, the number of factions means there is no guarantee of total buy-in from the opposition.
Other countries have put significant pressure on the rebels to put aside their differences. Reuters reports that Qatar and Turkey have brokered an agreement to unite the various factions fighting the Assad regime.
