"Armed terrorist" groups blasted Wednesday an oil pipeline in Syria's central Homs province which provided diesel fuel for the capital Damascus and the southern region, state-run SANA news agency reported.

The pipeline was blasted at 3.00 a.m. (0100 GMT) Wednesday in an area between restive Baba Amr and Sultania neighborhoods in Homs, said SANA, adding that the oil pipeline with a 12-inch diameter fed the Adra tankers.

On the opposition side, an activist group was cited by Arab TV stations as saying that the explosion occurred due to the shelling of the Syrian army on Baba Amr neighborhood.

At least seven pipelines have been targeted since the eruption of unrest in Syria in mid March 2011. Syria held what it called "saboteurs" responsible for the attacks.

Homs, Syria's third largest city and home to more than 800,000 people, has witnessed severe clashes between troops loyal to Syrian President Bashar al-Assad and militia groups allegedly comprising of Syrian army defectors.

The region is considered one of Syria's most volatile areas, as the daily grind of violence stocked fears that the area is sliding toward a civil war.

Earlier in January, Syrian Oil Minister Sufian Allaw said that the terrorist acts carried out by armed groups against oil pipelines and other oil institutions, in addition to the EU sanctions, have badly damaged Syria's oil sector.
