Syria's state news agency says "terrorists" have blown up a gas pipeline in central Syria.
There were no casualties.
The blast happened near the town of Rastan in restive Homs province.
SANA says the attack cuts off supplies to two power plants.
There have been several attacks on gas pipelines since protests against President Bashar al-Assad's regime began in March.
It is not clear who is behind the attacks. The government has blamed them on "terrorists" and "saboteurs."
The opposition says the regime is playing on fears of terrorism to rally support for Assad.
The United Nations estimates that more than 5,000 people heve been killed in the security crackdown on protests.
An Arab League foreign ministers' committee plans to meet on January 7 in Cairo to discuss a preliminary report from monitors sent to Syria to observe compliance with an Arab League-brokered plan to end 10 months of violence.
On January 2, Arab League Secretary-General Nabil Elaraby said the army had withdrawn heavy weapons from cities but admitted security forces were still killing protesters despite the presence of Arab League observers in the country.
