Syrian rebels have bombarded a military air base in Aleppo using a tank captured from government troops as activists reported that the regime has unleashed new raids against opposition fighters near the capital Damascus, killing dozens.
The Aleppo report was one of the first indications the rebels are starting to deploy the heavy weapons they've managed to capture in the past weeks from the Syrian army.
The Syrian Observatory for Human Rights said the rebel-seized tank shelled the Menagh military airport outside Aleppo, which the regime has used to launch attacks on rebel positions in the surrounding area.
Rami Abdul Rahman, the director of the Observatory, said it was not the first time the rebels have used the tanks they have captured by the regime.
It is, however, rare and represents an escalation in the battles between the two sides. Up to this point, rebel forces have suffered from the huge disparity in armaments with Syria's well-armed military that also has fighter jets and helicopter gunships at its disposal.
Rebel forces in northern Syria attacked the country's largest city of Aleppo two weeks ago and have captured several neighbourhoods, mostly lower income areas on the periphery, which they have since held despite ground and air assaults by the government. Residents reported today that internet and mobile phones were barely working.
With its proximity to rebel-friendly Turkey just to the north, Aleppo has enormous strategic importance to the opposition and if the rebels were able to capture and hold it, the city could form the kernel of a wider rebel-controlled zone.
"If Aleppo falls, then automatically we are going to establish headquarters at the presidential palace," said Burhan Ghalioun, a member of the opposition Syrian National Council, last night in Paris. "There will be nothing more that will stand in the way of the Free Syrian Army. Hama, Homs to the outskirts of Damascus have in large part been liberated."
The Syrian army, however, still has many more tanks and armoured vehicles than the rebels and there was no indication that today's attack on the airbase was effective. Later, a nearby village was shelled by government forces out of that same airbase.
There was also heavy shelling earlier in the day around the town of Azaz on the Turkish border, which has been in rebel hands for weeks along with a checkpoint crossing in the area, making it easier to deliver rebel weapons and supplies to the Aleppo battle. It would be a huge blow to the opposition if the government retook the crossing.
In the capital Damascus, the regime today announced a string of raids against rebels in neighbourhoods on the southern edge of the city, killing and arresting "a number of terrorists," as the government refers to rebels.
Operations also took place in the well to do Muhajireen district close to the presidential palace in Damascus and 20 people were arrested, according to activist Abu Qais, based in the Syrian capital.
A bold rebel assault on Damascus was crushed two weeks ago in fierce fighting, but the latest raids show that pockets of resistance remain in the capital and the surrounding countryside.
Abu Qais said that at least 20 people were killed by raids in the Yalda suburb, in the south, while the Observatory reported that 47 people had been killed in the Jdaidat Artouz neighbourhood to the south-west.
There has been a growing chorus of international condemnation of Syria's handling of the 17-month uprising, which activists estimate has taken 19,000 lives.
A vote is set for tomorrow in the UN General Assembly on a resolution drafted by Arab League countries, telling Syrian President Bashar Assad to step down and turn over power to a transitional government.
While the 193-member General Assembly has no legal mechanism for enforcing a resolution, an overwhelming vote can carry moral and symbolic power.
