(BEIRUT) — More than 3,000 Syrians were expected to be evacuated Sunday from four areas as part of a population transfer that was briefly stalled a day earlier by a deadly blast that killed more than 120 people, many of them government supporters.
As the evacuations were expected to begin Sunday, shells fired by the Islamic State group on government-held parts of the eastern city of Deir el-Zour wounded two members of a Russian media delegation visiting the area, according to state-run Syrian news agency SANA. Russia is a main backer of Syrian President Bashar Assad and Russian journalists enjoy wide access in government-held parts of the country.
The United Nations is not overseeing the transfer deal, which involves residents of the pro-government villages of Foua and Kfarya and the opposition-held towns of Madaya and Zabadani. All four have been under siege for years, their fate linked through a series of reciprocal agreements that the U.N. says have hindered aid deliveries.
Rami Abdurrahman, who heads the Britain-based Syrian Observatory for Human Rights, and Hezbollah’s Al-Manar TV said 3,000 people will be evacuated from Foua and Kfarya, while 200, the vast majority of them fighters, will be evacuated from Zabadani and Madaya.

Abdurrahman said Saturday’s blast —which hit an area where thousands of pro-government evacuees had been waiting for hours — killed 126. He said the dead included 109 people from Foua and Kfarya, among them 80 children and 13 women.
No one has claimed the attack, but both the Islamic State group and the al-Qaida-affiliated Fatah al-Sham Front have targeted civilians in government areas in the past.
A wounded girl, who said she lost her siblings in the blast, told Al-Manar TV from her hospital bed that children who had been deprived of food for years in the two villages were approached by a man in the car who told them to come and eat potato chips. She said once many had gathered, there was an explosion that tore some of the children to pieces.
After the blast, some 60 buses carrying 2,200 people, including 400 opposition fighters, entered areas held by rebels in the northern province of Aleppo, Abdurrahman said. More than 50 buses and 20 ambulances carrying some 5,000 Foua and Kfarya residents entered the government-held city of Aleppo, Syrian state TV said, with some of them later reaching a shelter in the village of Jibreen to the south.
U.N. relief coordinator Stephen O’Brien said he was “horrified” by the deadly bombing, and that while the U.N. was not involved in the transfer it was ready to “scale up our support to evacuees.”
He called on all parties to uphold their obligations under international humanitarian and human rights law, and to “facilitate safe and unimpeded access for the U.N. and its partners to bring life-saving help to those in need.”
Residents of Madaya and Zabadani, formerly summer resorts, joined the 2011 uprising against President Bashar Assad. Both came under government siege in the ensuing civil war. Residents of Foua and Kfraya, besieged by the rebels, have lived under a steady hail of rockets and mortars for years, but were supplied with food and medicine through military airdrops.
Critics say the string of evacuations, which could see some 30,000 people moved across battle lines over the next 60 days, amounts to forced displacement along political and sectarian lines.
In eastern Syria, an airstrike by the U.S.-led coalition on the village of Sukkarieh near the border with Iraq killed eight civilians who had earlier fled violence in the northern province of Aleppo, according to Deir Ezzor 24, an activist collective, and Sound and Picture Organization, which documents IS violations.
Airstrikes by the U.S.-led coalition had killed dozens of civilians over the past several weeks as the battle against the extremists intensifies in Syria and Iraq.
