At least 13 security forces and eight civilians have been killed in two separate bomb attacks in the northwestern Syrian city of Aleppo.
On Tuesday, a car bomb targeted a bus transporting Syrian law enforcement members near a gas station in Aleppo’s al-Shaar neighborhood.
The attack left at least four security forces and one civilian dead.
The second bomb exploded under a bridge in the city as a bus, which was also carrying troops, passed by. At least 16 people, including seven civilians, were killed in the assault.
Saudi and Qatari security officials are reportedly accused of being involved in such bombings in Syria. Both Arab states have openly expressed support for an armed insurgency campaign to overthrow the government of President Bashar al-Assad.
The blasts took place on the fifth day of a ceasefire in line with a six-point peace plan proposed in March by UN-Arab League envoy Kofi Annan.
On April 14, the UN Security Council passed its resolution 2042, authorizing the deployment of a team of up to 30 unarmed observers in Syria. However, the United Nations will seek approval for a larger group of about 250 observers under certain conditions.
Meanwhile on Sunday, a Syrian military official, whose name was not mentioned in news reports, said, “Armed terrorist groups have intensified their attacks in a hysterical way against the army, law enforcement forces, and civilians, in conjunction with the approval of the UN Security Council resolution to send monitors to Syria.”
Security forces “will prevent the terrorist groups from continuing their criminal attacks,” the official added.
Syria has been experiencing unrest since mid-March 2011. Many people, including numerous security forces, have been killed in the turmoil.
