Syria: What really happened in Jisr al-Shughour?

The Syrian authorities say more than 120 security personnel have been killed in clashes with armed gangs in the north-western town of Jisr al-Shughour. If confirmed, the violence would represent one of the bloodiest clashes in the uprising against President Bashar al-Assad.

Activist websites have not explained the unprecedented development. Some have suggested dissent within the armed forces, or even a mutiny. The 大象传媒's Jim Muir - reporting from Beirut - says, at the moment, it does look like there is some armed resistance going on, and there are reports the town is bracing for an onslaught by Syrian forces.

Amid conflicting accounts of what really happened - and with no foreign journalists being allowed in to verify the claims - the 大象传媒 compares the different versions of events.
