At least 19 civilians have been killed in a car bomb attack in a northern Syrian city controlled by Turkish-backed rebels, the BBC reports.
Eighty other people were injured when the vehicle exploded near a bus station in al-Bab, about 40 kilometers north-east of Aleppo city.
Rescue teams from the White Helmets said they are still searching for survivors in the rubble of damaged buildings, REL reports.
It is not yet known who is behind this attack.
However, there have been a number of attacks in al-Bab since the Islamic State (IS) extremist group was defeated and the region came under the control of rebels and Turkish troops in 2017.
Last November, an attack left 18 dead. Turkish authorities blamed the militants of the Syrian Kurdish People's Protection Units (YPG).
Ankara says that the Kurds in Syria belonging to the People's Protection Units have links with the Kurdish militants in Turkey of the Kurdistan Workers' Party (PKK), which it considers a terrorist organization.

However, the US claims that the YPG, which has helped them defeat the militant group, the Islamic State in Syria, is a separate entity from the PPK.
Two senior United Nations officials condemned the incident on Tuesday (October 6).
Imran Riza, humanitarian coordinator for Syria and Kevin Kennedy, regional humanitarian coordinator for the crisis in Syria, expressed their deepest condolences to the families of the victims and called on all parties to the Syrian conflict to adhere to their obligations to ensure security of civilians.
