Girls carry banners as they wait at Masnaa border crossing between Lebanon and Syria, for the arrival of their relatives, who are rebel fighters who left the town of Zabadani.

Around 450 Syrian fighters and their families were evacuated from two besieged areas on Monday under the kind of operation that the United Nations hopes can be a stepping stone towards a wider peace accord in the country’s civil war.

U.N. and airport sources said two planes with 330 Syrian Shiite fighters and civilians evacuated from two pro-government towns in northwestern Syria arrived in Beirut airport. Hundreds of Hezbollah supporters there set off fireworks in celebration.

Another plane carrying 126 mostly Sunni Muslim rebel fighters trapped in Zabadani near the Lebanese border landed at Hatay airport in southern Turkey, the sources said.

The evacuations took place under a U.N.-sponsored agreement brokered by regional powers, part of efforts by the United Nations to set up local deals on ceasefires and safe passage.

In return for allowing the rebels to leave, the deal allows the government of President Bashar al-Assad to restore control over areas that had been in rebel hands for the past four years.

In Zabadani, a once popular resort city now in ruins, relief workers and rebel fighters who have been holed up for months helped carry wounded young men in wheelchairs onto ambulances.

Relatives and well-wishers who had waited for hours on the Lebanese border cheered buses carrying the fighters as they drove by towards Beirut airport, and some families wept as they strained for glimpses of their loved ones, a witness said.

Zabadani, northwest of the capital Damascus, was one of the rebels’ last strongholds along the border. Much of the town was devastated in a major offensive launched in July against the insurgents by the Syrian army and its Lebanese Hezbollah allies. Only several hundred rebels remain in the town, where most civilians have fled to nearby Madaya.

Food and aid

The evacuation deal was the most significant of several localized truces to date, involving months of mediation among warring parties.

Under the next stage, trucks loaded with humanitarian goods and basic foodstuffs will be allowed through in the next few days to reach thousands of civilians still trapped, Yacoub El Hilo, U.N. resident and humanitarian coordinator in Syria, told reporters.

“As the United Nations and international community, these agreements and truces are the foundations for building something bigger that could cover all of Syria,” El Hilo said.

“We support these accords as they have a positive impact on civilians and help bring aid and the return of normality.”

However years of government siege of rebel held areas with large civilian populations to force insurgents to enter into truces has impeded the flow of food and humanitarian aid, starving many people to death in what rights group Amnesty International has described as a war crime.

The U.N.’s Syria mediator aims to convene peace talks in Geneva on Jan. 25 in the latest effort to end nearly five years of civil war in which more than 250,000 people have died.

Iran, which backs Assad’s government, and Turkey, which backs the rebels, helped organize local ceasefires in Zabadani and the two villages in Idlib in September in the first phase of the deal, overseen by the International Committee of the Red Cross.

The mostly Sunni Muslim rebel fighters going to Turkey from Zabadani would then be able to go back to rebel-held areas in Syria through the northern Turkish border or stay for treatment, according to rebel sources close to the negotiations.

The Shi’ite Syrians leaving the besieged towns in the north where at least 25,000 civilians still live would be able to get to Lebanon, where Hezbollah would be able to watch over them, added the sources.

They are then expected to go back to other parts of Syria, Syrian Minister of National Reconciliation Ali Haider said on Hezbollah’s Manar TV station on Monday.

In another local deal earlier this month, Syrian government officials said they had agreed for rebel fighters to withdraw with their weapons from the last insurgent-held area of the city of Homs. Despite that, there have been two major bomb attacks in the city in the last two weeks.

Another deal, which sought to extract over 2,000 ISIS fighters from south Damascus, ran aground last week, a day after a top rebel commander was killed in an air strike.
