A suspected missile strike on an oil-loading facility used by Turkey-backed opposition forces in northern Syria has sparked a massive blaze across a large area where oil tankers are normally parked, aerial and satellite images show.

Syrian opposition groups and at least one war monitor blamed Russia for the strike on Friday night near the towns of Jarablus and al-Bab, near the border with Turkey.

In a report, the Syrian Observatory for Human Rights, based in Britain, said Russian warships in the Mediterranean had fired three missiles that struck primitive oil refineries and tanker trucks in the region.

It said more than 180 trucks and tankers were burned in the massive blaze, and at least four people killed and 24 wounded.

Photos and videos from the air taken by the Syrian opposition’s civil defence group known, as the White Helmets, showed scores of workers struggling to extinguish a massive fire resulting from burning oil tanker trucks in an open field, as smoke covered the area.

Satellite images by Planet Labs analysed by the Associated Press on Sunday also showed the aftermath of a large fire that tore through an area near Jarablus between Friday and Saturday morning.

Past satellite photos of the site, some 45 miles north-east of the Syrian city of Aleppo, showed hundreds of tanker trucks gathered in the area.

An image from Saturday showed char marks across the entire area where the trucks once were. Nasa’s fire satellite monitoring, which watches for flashes associated with blazes or explosions, showed fires at the site in the early morning hours of Saturday.

The reports of missiles fired from a Russian warship – a rare occurrence – could not be independently verified and Russia, which is a main supporter of Syrian President Bashar Assad in the country’s 10-year civil war, has not commented on the accusations.

Turkey’s state-owned Anadolu news agency reported they were ballistic missiles, but said it was not clear who carried out the attacks.

Turkey and allied Syrian opposition fighters control large parts of northern Syria.
