Syria on Wednesday released from jail 755 prisoners who had been involved in anti-regime unrest, state television said, as Arab observers deployed in flashpoint hubs to implement a peace deal.

"Seven hundred and fifty-five prisoners who had been involved in the recent incidents in Syria and who did not have Syrian blood on their hands have been released" from prison, the state broadcaster said in a news flash.

In November, Syria announced it had freed 1,180 prisoners citing similar conditions.

Releasing prisoners is one of the key conditions of an Arab League roadmap approved by Syria last month to end the country's crisis. The accord also calls for an end to repression of pro-democracy protests.
