BEIRUT: Five Syrian rescue workers were killed in an attack by masked assailants on Saturday on one of their centres in the northern province of Aleppo, the White Helmets said.

The rescue force said armed men stormed its Al-Hader centre in a pre-dawn attack and fired on the first responders inside.

Four volunteers were killed on the spot and a fifth died later in hospital, it wrote on Twitter.

Founded in 2013, the White Helmets are a network of first responders who rescue wounded in the aftermath of air strikes, shelling or blasts in rebel-held territory.

The Al-Hader centre lies in an area controlled by Hayat Tahrir al-Sham (HTS), a jihadist organisation whose main component was once Al Qaeda’s affiliate in Syria.

“At around 2am, an armed group stormed the Al-Hader centre, blindfolded the staff members who were on the night shift, and killed five of them,” said Ahmad al-Hamish, who heads the centre.

“Two others were wounded and another two were able to flee. The attackers were masked and escaped after stealing some equipment and generators,” he said.

It was unclear whether the attack was a robbery-gone-wrong or if the centre and its crew had been specifically targeted.

More than 200 White Helmets rescuers have been killed in Syria’s seven-year war, usually in bombing raids or shelling on their centres.

While attacks like the one on Saturday are rare, they have happened before.

In August, seven White Helmets members were killed in a similar assault in the town of Sarmin, in neighbouring Idlib province.

Most of Idlib is held by HTS, as well as a part of Aleppo and the adjacent province of Hama.

Tensions are on the rise there, with a wave of intra-opposition assassinations and clashes leaving at least 20 rebels dead in 48 hours, according to the Syrian Observatory for Human Rights.

“You cannot separate the Al-Hader incident from the assassinations and other killings that have been happening more and more in recent weeks in areas under HTS control,” said Observatory head Rami Abdel Rahman.
