AMMAN: Syrian authorities closed Aleppo airport and canceled all flights on Saturday, three military sources told Reuters, as rebels opposed to President Bashar Assad said they had reached the heart of the city.
The opposition fighters, led by the Islamist militant group Hayat Tahrir Al-Sham, carried out a surprise sweep through government-held towns this week and reached Aleppo nearly a decade after having been forced out of the northern Syrian city.
Russia, a key ally of Assad, has promised Damascus extra military aid to thwart the rebels, two military sources said, adding new hardware would start arriving in the next 72 hours.
The rebels began their incursion on Wednesday and by late Friday an operations room representing the offensive said they were sweeping through various neighborhoods of Aleppo.

They are returning to the city for the first time since 2016, when Assad and his allies Russia, Iran, and regional Shiite militias retook it, with the insurgents agreeing to withdraw after months of bombardment and siege.
Mustafa Abdul Jaber, a commander in the Jaish Al-Izza rebel brigade, said their speedy advance this week had been helped by a lack of Iran-backed manpower in the broader Aleppo province. Iran’s allies in the region have suffered a series of blows at the hands of Israel as the Gaza war has expanded through the Middle East.
Opposition sources in touch with Turkish intelligence said Turkiye had given a green light to the offensive.
But Turkish foreign ministry spokesperson Oncu Keceli said Turkiye sought to avoid greater instability in the region and had warned recent attacks undermined de-escalation agreements.
The attack is the biggest since March 2020, when Russia and Turkiye agreed to a deal to de-escalate the conflict.

CIVILIANS KILLED IN FIGHTING
On Friday, Syrian state television denied rebels had reached the city and said Russia was providing Syria’s military with air support.
The Syrian military said it was fighting back against the attack and had inflicted heavy losses on the insurgents in the countryside of Aleppo and Idlib.
David Carden, UN Deputy Regional Humanitarian Coordinator for the Syria Crisis, said: “We’re deeply alarmed by the situation unfolding in northwest Syria.”
“Relentless attacks over the past three days have claimed the lives of at least 27 civilians, including children as young as 8 years old.”
Syrian state news agency SANA said four civilians including two students were killed on Friday in Aleppo by insurgent shelling of university student dormitories. It was not clear if they were among the 27 dead reported by the UN official.
Kremlin spokesman Dmitry Peskov said on Friday that Moscow regarded the rebel attack as a violation of Syria’s sovereignty.
“We are in favor of the Syrian authorities bringing order to the area and restoring constitutional order as soon as possible,” he said.

KARBALA: Rami, a Syrian worker in Iraq, spends his 16-hour shifts at a restaurant fearing arrest as authorities crack down on undocumented migrants in the country better known for its own exodus.
He is one of hundreds of thousands of foreigners working without permits in Iraq, which, after emerging from decades of conflict, has become an unexpected destination for many seeking opportunities.
“I’ve been able to avoid the security forces and checkpoints,” said the 27-year-old, who has lived in Iraq for seven years and asked that AFP use a pseudonym to protect his identity.
Between 10 in the morning and 2 a.m. the next day, he toils at a shawarma shop in the holy city of Karbala, where millions of pilgrims congregate every year.
“My greatest fear is to be expelled back to Syria, where I’d have to do military service,” he said.

The Labor Ministry says the influx is mainly from Syria, Pakistan, and Bangladesh, also citing 40,000 registered immigrant workers.
Now, the authorities are trying to regulate the number of foreign workers as the country seeks to diversify from the currently dominant hydrocarbons sector.
Many, like Rami, work in the service industry in Iraq.
One Baghdad restaurant owner admitted that he has to play cat and mouse with the authorities during inspections, asking some employees to make themselves scarce.
He said that not all those who work for him are registered because of the costly fees involved.
Some of the undocumented workers in Iraq first came as pilgrims. In July, Labour Minister Ahmed Assadi said his services investigated information that “50,000 Pakistani visitors” stayed on “to work illegally.”
Despite threats of expulsion because of the scale of the issue, the authorities, at the end of November, launched a scheme for “Syrian, Bangladeshi, and Pakistani workers” to regularize their employment by applying online before Dec. 25.
The ministry says it will take legal action against anyone who brings in or employs undocumented foreign workers.
Rami has decided to play safe, even though “I want” to acquire legal employment status.
“But I’m afraid,” he said. “I’m waiting to see what my friends do, and then I’ll do the same.”
Current Iraqi law caps the number of foreign workers a company can employ at 50 percent, but the authorities now want to lower this to 30 percent.
“Today we only allow qualified workers for jobs requiring skills” that are not currently available, Labor Ministry spokesman Nijm Al-Aqabi said.
It’s a sensitive issue — for the past two decades, even a foreign workforce has dominated the robust oil sector. But now the authorities are seeking to favor Iraqis.
“There are large companies contracted to the government” which have been asked to limit “foreign worker numbers to 30 percent,” said Aqabi.
“This is in the interests of the domestic labor market,” he said, as 1.6 million Iraqis are unemployed.
He recognized that each household has the right to employ a foreign domestic worker, claiming this was work Iraqis did not want to do.
One agency launched in 2021 that brings in domestic workers from Niger, Ghana, and Ethiopia confirms the high demand.
“Before, we used to bring in 40 women, but now it’s around 100” a year, said an employee at the agency.
The employee said it was a trend picked up from rich countries in the Gulf.
“The situation in Iraq is getting better, and with higher salaries, Iraqi homeowners are looking for comfort.”
A domestic worker earns about $230 a month, but the authorities have quintupled the registration fee, with a work permit now costing more than $800.
In the summer, Human Rights Watch denounced what it called a campaign of arbitrary arrests and expulsions targeting Syrians, even those with the necessary paperwork.
HRW said that raids targeted both homes and workplaces.
Ahmed — another pseudonym — is a 31-year-old Syrian who has been undocumented in Iraq for the past year and a half.
He began as a cook in Baghdad and later moved to Karbala.
“Life is hard here — we don’t have any rights,” he said
“We come in illegally, and the security forces are after us.”
His wife did not accompany him. She stayed in Syria.
“I’d go back if I could,” said Ahmed. “But life there is very difficult. There’s no work.”
