Syrian President Bashar al-Assad today, Sunday, flew out of Damascus for an unknown destination.

This was disclosed by two senior army officers who spoke to Reuters, as rebels said they had entered the capital with no sign of army deployments.

Thousands in cars and on foot congregated at a main square in Damascus waving and chanting “Freedom”, witnesses said.

“We celebrate with the Syrian people the news of freeing our prisoners and releasing their chains and announcing the end of the era of injustice in Sednaya prison,” said the rebels.

Sednaya is a large military prison on the outskirts Damascus where the Syrian government detained thousands.

A Syrian Air plane took off from Damascus airport around the time the capital was reported to have been taken by rebels, according to data from the Flightradar website.

The aircraft initially flew towards Syria’s coastal region, a stronghold of Assad’s Alawite sect, but then made an abrupt U-turn and flew in the opposite direction for a few minutes before disappearing off the map.

Just hours earlier, rebels announced they had gained full control of the key city of Homs after only a day of fighting, leaving Assad’s 24-year rule dangling by a thread.

Intense sounds of shooting were heard in the centre of the Damascus, two residents said on Sunday, although it was not immediately clear what the source of the shooting was.

In rural areas southwest of the capital, local youths and former rebels took advantage of the loss of authority to come to the streets in acts of defiance against the Assad family’s authoritarian rule.

Thousands of Homs residents poured onto the streets after the army withdrew from the central city, dancing and chanting “Assad is gone, Homs is free” and “Long live Syria and down with Bashar al-Assad”.

Rebels fired into the air in celebration, and youths tore down posters of the Syrian president, whose territorial control has collapsed in a dizzying week-long retreat by the military.

The fall of Homs gives the insurgents control over Syria’s strategic heartland and a key highway crossroads, severing Damascus from the coastal region that is the stronghold of Assad’s Alawite sect and where his Russian allies have a naval base and air base.

Homs’ capture is also a powerful symbol of the rebel movement’s dramatic comeback in the 13-year-old conflict. Swathes of Homs were destroyed by gruelling siege warfare between the rebels and the army years ago. The fighting ground down the insurgents, who were forced out.
