Syria regime forces launch new Aleppo offensive

Syrian government troops began a new offensive around the northern city of Aleppo on Tuesday, attacking a string of villages in an attempt to encircle rebel fighters, a monitor said.
The offensive comes the same day that UN peace envoy Staffan De Mistura is to address the Security Council on his efforts, including a plan to "freeze" fighting in Aleppo that has so far failed to gain traction.
The Britain-based Syrian Observatory for Human Rights Monitor said government troops had seized two villages north of Aleppo and were engaged in fierce fighting for control of a third.
The villages are strategically located alongside a road that serves as a key supply route for the rebels, leading from the east of Aleppo to the border with Turkey.
At least 12 rebels were killed in the fighting for the villages, the Observatory said, adding that the clashes had stopped traffic on the key highway.
As they launched the attacks, government forces also began shelling two towns on the road to Nubol and Zahraa, both government-held Shiite villages.
Nubol and Zahraa have been under rebel siege for more than 18 months, and pro-government militants inside the villages have repelled several attacks.
"The regime troops have two goals in the area: to cut the road leading from Aleppo to the Turkish border, which is the key supply road for the rebels, and to open the way to Nubol and Zahraa," Observatory director Rami Abdel Rahman said.
The offensive in northern Aleppo province was also accompanied by renewed fighting inside Aleppo city, which is divided between rebel and regime control.
The Observatory reported fierce clashes in several parts of the government-controlled west of the city, where at least six rebels were killed.
Rebel rocket fire into several western neighbourhoods also killed eight civilians, the monitor said, among them a child.
- Aleppo divided -
Once Syria's industrial powerhouse, Aleppo has been split between rebel control in the east and regime control in the west since shortly after fighting began there in mid-2012.
In the surrounding countryside the situation is largely the reverse, with rebels controlling much of the area west of the city and regime forces much of the east.
Government forces advanced around the east of the city last year, but the front lines had been relatively static in recent weeks.
On Monday, the Observatory reported an influx of regime reinforcement and the Syrian daily Al-Watan, which is close to the government, said regime forces planned to encircle the city in a new offensive.
"Aleppo is very important for us," a Syrian military source told AFP on Tuesday.
"The main goals are to break the siege of Aleppo and open the road to Nubol and Zahraa," he added.
The new offensive comes shortly after regime forces opened a new front in southern Daraa province.
"This military operation in Aleppo proves the ability of the Syrian army to open multiple fronts at once," the military source said.
The offensive began as UN envoy De Mistura prepared to address the Security Council.
He has advanced a plan for a "freeze" to the fighting in Aleppo, in a bid to ease the humanitarian situation and provide an example for ceasefires elsewhere.
But the proposal has gained little traction, and De Mistura drew criticism from the opposition last week after describing Syria's President Bashar al-Assad as "part of the solution" to the conflict.
The rebels and opposition insist Assad's departure is a precondition for resolving the country's brutal war, which began in March 2011 with peaceful anti-government protests.
It spiralled into a civil conflict after a government crackdown, and the violence has killed more than 210,000 people.
