Beirut: Armed men attacked Syrian security forces in a tense northern city on Tuesday, state television said. Around 120 policemen and security forces were killed in a region where the Army has carried out  deadly assaults on protesters calling for the end of President Bashar Assad's rule.

Communications were snapped in the area around Jisr al-Shughour on Tuesday and the details of the attack were impossible to verify but there have been unconfirmed reports in the past by residents and activists of Syrians fighting back against security forces.

The government promised a "decisive" response setting stage for an even stronger crackdown against a popular uprising that began in mid-March which poses the most potent threat to the 40-year regime of the Assad family.

"We will deal strongly and decisively and according to the law, and we will not be silent on any armed attack which targets the security of the state and its citizens," said Interior Minister Ibrahim Shaar.

Jisr al-Shughour, near the Turkish border, has been the latest focus of Syria's military, whose nationwide crackdown on the revolt has left more than 1,200 Syrians dead, activists say.

The town was sometimes the stronghold of country's banned Muslim Brotherhood in the 1980s.Human rights groups said at least 42 civilians have been killed there since Saturday.
