At least three people were killed Thursday in a series of explosions, including two suspected suicide bombings, in northwest Syria near the Turkish border, witnesses said, in the first such attacks this year.
A rescue worker said one civilian was killed when an improvised explosive device went off in a vehicle near a transport office in the city of Azaz, near the main border crossing with Turkey.
A few hours later, a suicide bombing in a marketplace in the town of al-Bab wounded three and killed the suspected bomber, a police source said.
This was followed minutes later by another suicide bombing at a roundabout in the city of Afrin, a mainly Kurdish area that Turkish forces and their Syrian allies took from the Kurdish YPG militia in 2018.
Main towns in the northwestern border area, run by Syrian Arab rebels backed by Turkey, have in the last year been frequently hit by bombings detonated in crowded civilian areas.
Turkey and its allied rebels say the blasts aim to make ungovernable an area populated by more than 3 million Syrians who have fled government-controlled areas during the country's decadelong civil war.
Turkish-backed Arab rebels in Azaz and other parts of the enclave have blamed previous blasts on the YPG, which controls some areas in the northwest and holds sway over swaths of Syria's northeast.
The YPG has in turn accused Turkey of killing civilians in drone strikes during a war of attrition waged by Ankara over YPG-held territory in north Syria.
Turkey considers the YPG an extension of the Kurdistan Workers' Party (PKK), which Ankara designates a terrorist group, and has made incursions into Syria in support of Syrian rebels.
Ankara retains a large military presence in the area, deploying thousands of troops in what is the last rebel enclave.
