Two Oxfam aid workers were killed in an attack that targeted their vehicle in Syria on Wednesday, the NGO said.

They were targeted by unidentified gunmen on the Yadoda–Muzayrib road in the western countryside of Daraa.

This is the first time that aid workers get killed in this area where the number of attacks and assassination attempts keep on rising in various methods.

More than 303 attacks took place in the area under different forms, including detonating bombs, mines, booby-trapped cars, and firing with light and medium weapons.

According to the Syrian Observatory for Human Rights, these attacks killed 194 people, 38 were civilians including four women and two children.

Meanwhile, almost 100 were from the regime forces and militiamen loyal to them and collaborators of the security forces and regime institutions. Also, 16 Syrian militias of Lebanon's ''Hezbollah'' and the Iranian forces were killed in these attacks, in addition to six of what is known as the 5th Corps which was established by Russia.
