AL-TAMANA, SYRIA (AFP) - Intense fighting killed dozens of people on the edge of the last Syrian province entirely outside government control as aid workers completed a series of medical evacuations from another rebel-held area on Friday (Dec 29).
Government and allied forces backed by Russian warplanes took on mostly Islamist fighters in an area straddling the border between Idlib and Hama provinces.
The fighting, which could signal the start of a major offensive to wrest Idlib province from rebels dominated by a former Al-Qaeda affiliate, escalated on Thursday.
Since then, at least 68 people have been killed in the ongoing clashes centred around an area called Al-Tamana, said the Syrian Observatory for Human Rights.
Among them were at least 21 civilians, said Mr Rami Abdel Rahman, who heads the Britain-based monitor.
They were killed in air strikes carried out by Russian warplanes and by barrel bombs dropped by Syrian aircraft, he said.
Twenty-seven soldiers and members of allied paramilitary units were killed in the fighting, as well as 20 rebels from Islamist groups or from former Al-Qaeda affiliate Fateh al-Sham, he added.
Mr Abdel Rahman said the latest deaths brought the number of civilians killed in the area since Monday to 42 and the death toll among combatants to 90.
An AFP correspondent near the front line said aerial activity was intense and the entire area rocked by frequent air strikes.
Through loudspeakers, rebel leaders warned remaining civilians that Friday Muslim prayers were cancelled and all residents should stay home.
Hundreds of civilians fled the scattering of villages in the area, creating queues of cars and pickup trucks loaded down with bags and furniture on the roads towards the city of Idlib.
South-east of Al-Tamana, a Syrian cameraman working for pro-regime TV network Sama was killed on Friday when his crew was targeted by "terrorists" near the village of Umm Haratain, state news agency SANA said.
"The air strikes haven't been that intense in months in this area," said Mr Abdel Rahman, adding that the immediate goal of the latest regime push was to retake control of the southeast of the province.
The Islamic State in Iraq and Syria (ISIS) terror group, which proclaimed a "caliphate" over swathes of Syria and Iraq in 2014, has now lost almost all the land it once controlled.
But other factions opposed to the regime of President Bashar al-Assad still control pockets scattered across Syria, the largest one being Idlib province, which borders Turkey.
Another is Eastern Ghouta, a small enclave east of the capital Damascus, which is controlled mostly by rebels from the Jaish al-Islam group and where around 400,000 residents still live.
The humanitarian situation there has deteriorated sharply in recent months and on Friday, aid workers completed a series of medical evacuations of some of the most critical cases.
The last 13 in a group of 29 priority patients have now been evacuated, together with 56 members of their entourage, a health official said.
They were deemed among the most pressing cases on a list of around 500 people the United Nations said last month could die without urgent treatment outside the enclave, which has been besieged for four years.
Among them was Ms Marwa, a 26-year-old woman suffering from meningitis, and Mr Zuheir Ghazzawi, a 10-year-old boy with cancer who has had a leg amputated.
The Observatory said the patients were evacuated as part of a deal that saw the rebels who control Eastern Ghouta release hostages and prisoners.
There were also 29 of them, including workers who were detained earlier this year and pro-government fighters captured by rebels in the area, in some cases years ago.
The International Committee of the Red Cross welcomed the evacuation as "a positive step".
"But more needs to be done. The needs of civilians should come first, be it in Ghouta or elsewhere in Syria, and access to aid should be allowed on a more regular basis and without conditions," said the ICRC's Syria chief Marianne Gasser.
Dozens of Islamist and rebel fighters were meanwhile evacuated from a key stronghold near Damascus under a deal with the Syrian regime, state television reported.
It said 10 buses "transported Al-Nusra fighters and members of their families from Western Ghouta" towards Idlib and Daraa provinces.
Al-Nusra Front now calls itself Fateh al-Sham Front. It is a former Al-Qaeda affiliate that dominates the northern province of Idlib.
State news agency SANA reported that dozens of bodies of civilians and Syrian troops killed by ISIS extremists had been found in two mass graves in the west of Raqqa province.
It was not immediately clear when they had been killed or how many bodies there were in total.
