Damascus: As many as 80 policemen were killed after hundreds of gunmen ambushed a convoy of police in Jisr al-Shughour in Idleb province of Syria, reported a news agency. The incident took place, when the cops were on their way to control unrest.

Armed groups also attacked a security centre and a number of government buildings and burned down a few of them.

The insurgents stole around five tonnes of dynamite from a storage building.  Security reinforcements have reached the area to protect civilians.

Syria has been engulfed since March with a wave of protests, calling for reforms and more freedom in the country.

President Bashar al-Assad had initially responded to the anti-government protests by offering some concessions, including lifting the emergency in place since 1963, releasing hundreds of political detainees and reshuffling the government.
