Fifty-seven people were killed Sunday in the Syrian city of Homs in two car bomb explosions.
“Islamic State” (IS) claimed responsibility for the attacks, which injured other 100 people, in the Al-Zahraa district.
Photographs were published by state television following the attacks, showing dead bodies and destroyed buildings in Homs.
The IS militant groups released a statement claiming responsibility for the operation.
Last month, the group claimed responsibility for an attack in Homs, which killed 24 people.
The attack follows advances by regime troops against IS in a number of locations.
Violence in Syria continues, as the UN is trying to bring both the regime and the opposition back to peace talks in Geneva.
The first round of the talks was suspended due to the ongoing Russian airstrikes on Syrian cities controlled by the opposition.
