Syrian media released video footage of the mutilated and charred bodies on Saturday.
This is not the first time armed groups kill civilians and security personnel in Homs. Last month, a number of mutilated bodies belonging to security forces were pulled out of the sewage system in Homs.
Meanwhile, the United Nations Security Council has unanimously passed a resolution allowing a 300-strong ceasefire monitoring mission in Syria.
The ceasefire announced on April 12 is part of a six-point peace plan proposed by the UN-Arab League envoy Kofi Annan in March.
An advance team of United Nations observers visited Syria’s central province of Homs today. The observers met with the provincial governor and toured the Baba Amr neighborhood in the city of Homs.
The city of Homs, the provincial capital, has been the scene of heavy clashes between Syrian forces and armed groups earlier in the year.
Syria has been experiencing unrest since mid-March 2011. Many people, including security forces, have been killed in the turmoil.
