CNN — Lakhdar Brahimi, the U.N. and Arab League point man who has been shuttling among capitals in an attempt to broker a halt to the war in Syria, said Thursday he is pinning his hopes on the formation of a transitional government in Damascus that would hold power until an election.
A June 30 communique issued in Switzerland by world powers would provide a template for Syrian-led political change and an end to the carnage in an Arab land torn daily by fighting, misery and chaos, Brahimi told reporters in Damascus.
"The situation in Syria now presents a grave danger; not just to the Syrian people, but also to the neighboring countries and the world," he told reporters Thursday in the Syrian capital. "Time is in no one's favor."
The so-called Geneva plan united countries that had been at odds on how to handle the crisis. Russia and China joined France, Britain, the United States and Turkey in agreeing on the plan. Arab League nations also signed on to it.
"The Geneva conference held in June this year includes elements that are sufficient for a plan to end the crisis in the next few coming months," he said. "It was clear in Geneva and it is now clearer that the change required is not cosmetic. Syria and the Syrian people need, want and look forward to real change."
World powers have been seeking a solution to the 21 months of conflict in Syria. There's widespread support for President Bashar al-Assad leaving power in any change of government.
Brahimi foresees a transitional government with "full executive powers" that would govern during "the transitional period, which will end with elections."
"The transitional period should not be allowed to lead to the collapse of the state and its institutions. On the contrary, everyone should cooperate -- the Syrians and those who assist them -- to preserve these institutions and to rebuild and strengthen them," he said.
Brahimi said violence must stop and "strong observation" by a peacekeeping mission would be key.
"When we reach a stage of speaking about peacekeeping forces, it means that there is an agreement, and thankfully, the parties have agreed that they need these forces," he said.
"No one will bring forces into Syria from a country that is not approved by either of the Syrian parties."
A key question from Geneva is whether al-Assad could be part of a transitional government.
According to the communique, the transitional government "could include members of the present government and the opposition and other groups and shall be formed on the basis of mutual consent."
But Thursday, a spokesman for the opposition Syrian National Coalition, Walid al Bunni, told reporters in Istanbul, "The Syrian opposition will never accept any initiative to solve the crisis in Syria if it doesn't involve Assad stepping down."
Over the last few weeks, Brahimi has held discussions with Syrian, Russian and U.S. officials, and is expected to visit Moscow on Saturday. Russia's role in forging peace is key because Moscow has confounded Western and Arab nations by blocking tough action in the U.N. Security Council against Syria, its longtime ally.
Russia has had good relations with the Assad regime, but it has grown angry with the warfare and wants to resolve a conflict that has left more than 40,000 people dead.
"In our talks with Brahimi and with our American colleagues, we are trying to feel a way out of this situation on the basis of our common plan of action that was agreed on in Geneva in June," Russian Foreign Ministry spokesman Alexander Lukashevich said, according to state-run RIA Novosti.
"We plan to discuss a range of issues linked to a political and diplomatic settlement in Syria, including Brahimi's efforts aimed at halting the violence and the start of a comprehensive national dialogue."
Lukashevich said he was not ruling out engaging with the Syrian National Coalition, the opposition movement recognized by nations opposed to the Assad government.
"But when and at what level, that's an entirely different matter," he said, according to RIA Novosti.
Brahimi told reporters that the plight of displaced people reflects the misery that exists throughout Syria. Since the civil war began last year, more than 540,000 refugees have spilled into nearby countries such as Jordan, Turkey, Iraq, Lebanon and Egypt.
"When we say there are  million internally displaced, what does it mean? It means that there are children and women who have nowhere to sleep, nothing to eat and are roaming the streets. We should thank their Syrian brethren who, in many cases, share their bread with them. These 4 million people are in need for bread and medicine," he said.
"You must have seen on TV boys breaking their desks in school to bring some wood for their families for heat. This is the meaning of what is happening in Syria."
With host countries strained and winter settling in on refugee camps, the crisis is expected to worsen.
The U.N. humanitarian affairs office says the number of refugees is expected to double next year to 1.1 million.
"These figures insufficiently express the suffering of the Syrian people and the injustice they suffer from," Brahimi said. "And, therefore, those who can have mercy on the Syrian people should do so. This is what we should not forget. We do not speak in a vacuum or about theoretical things; we are speaking about humans of flesh and blood, men, women, elderly, young children."
The number of deaths in Syria rose Thursday by 180, including 97 in Damascus and its suburbs and 50 others found in a refrigerated truck on the Damascus-Daraa highway, the Local Coordination Committees of Syria said. The 50 had been "field executed by regime forces," the opposition group said.
CNN cannot independently verify opposition and government reports from Syria, as the government has restricted international journalists' access.
