Forty-four people were killed in a double bombing in a Kurdish-controlled city of Qamishli in north-east Syria on Wednesday, Syrian state TV reports.

One of the blasts was caused by a truck bomb which struck near a Kurdish security headquarters, according to a UK-based monitoring group.

So-called Islamic State (IS) has said it was behind the attack, in Hassakeh province, near the border with Turkey.

IS has previously carried out bombings against Kurds in the area.

Last year, a US-backed alliance led by Kurdish fighters, the Syrian Democratic Forces (SDF), launched an offensive against IS in Hassakeh.

State TV said explosives in a vehicle and a motorbike were detonated in Wednesday's attack.

It showed scenes which it said were the aftermath of one of the bombings, with pictures of destruction over a large area and plumes of smoke rising into the air.

IS said on its self-styled Amaq news agency that a suicide bomber had blown up a truck bomb at a local Kurdish police centre and a nearby government building.
