An "armed terrorist group" blasted late Monday a gas pipeline in Syria's central province of Homs, causing temporary halt of gas delivery, according to official SANA news agency.

The blast also led to the leakage of a large amount of gas which caused huge fire, SANA said, adding that there were no casualties in the explosion.

Monday's blast was the second attack on the gas pipeline in Homs in a week, as a "terrorist group" blew up last Thursday a pipeline in the violence-hit province.

A number of pipelines have been targeted since the eruption of unrest in Syria in mid March. Syria held what it called "saboteurs" responsible for the attacks.

In a separate incident on Monday, Syrian border guards thwarted an infiltration attempt of 15 gunmen, who tried to sneak into Syria from Turkey, and killed two of them, according to SANA.

Monday's clash came following another infiltration attempt last week of 35 gunmen who tried to sneak into Syria, but the border guards forced them to return to Turkey.

Also on Monday, an "armed terrorist group" assassinated an army brigadier in a suburb of the northern province of Idlib, according to SANA.

Syria has blamed armed thugs for fueling sectarian rivalries in the country that has a complex mosaic of sects and ethnicities.

Syrian President Bashar al-Assad recently said about 1,100 members of the armed forces were killed during the unrest which started in March, while the United Nations put the number of the victims at 4,000.
