A person affiliated with Iraq's Hezbollah Brigades armed group was killed Friday in a strike targeting pro-Iran factions in Syria, a group member said, blaming Israel for the attack.
The Syrian Observatory for Human Rights war monitor said a Hezbollah Brigades member was killed, but was unable to verify the strike itself.
The Britain-based monitor, which relies on a network of sources on the ground in Syria, said the member's burned-out vehicle was found about 10 kilometres (six miles) from Damascus airport.
The Hezbollah Brigades member said the Israeli raid hit one of the group's premises, killing Abu Haidar al-Khafaji, a senior member of the group.
Another member was reportedly wounded in the attack.
The Observatory said the strike occurred about five kilometres from Sayeda Zeinab, on the outskirts of the Syrian capital.
Its director, Rami Abdel Rahman, said a militant was killed but yet to be identified, and the burnt vehicle was found at dawn near the targeted site.
