At least 26 people including 12 children were killed in a car bombing in an area of the eastern Syrian province of Deir Ezzor where numerous refugee families were gathered, a rights monitoring group reported on Friday.
The Islamic state jihadist group was responsible for the attack which took place between al-Jafra and al-Koniko, according to the UK-based Syrian Observatory for Human Rights.
State-run Syrian news agency Sana also reported the blast, saying that 20 people had been killed and 30 injured "due to a car bombing carried out by Daesh," the Arabic acronym for IS.
Sana and the Observatory reported a car bombing, allegedly also carried out by IS, which targeted refugees in the same area on 4 November. Seventy-five people were killed in the earlier attack, activists said.
