“Considering the fracture pattern, seen in the pictures and videos taken at the site, the camp could have been shelled, either intentionally or by mistake, by rocket artillery, which is in active use in the area by militants from the terror group Al-Nusra Front,” Major-General Igor Konashenkov, Russian Defense Ministry spokesman, said on Friday.

He added that after analyzing photographs and video footage from the devastated camp available online, it became evident that “there are no airstrike shell craters or other signs of an airstrike.”

The Russian Defense Ministry states there were no air sorties over the area of the refugee camp on the day of the attack or on the day prior to it.

“We have analyzed airspace objective control data for the area as of May 4 and 5, 2016. There were no flights of Russian or any other aircraft over the camp area,” Konashenkov stressed.

“Since [Thursday] many international media outlets, citing the UK-based Syrian Observatory for Human Rights, have been reporting an airstrike that hit the refugee camp in Northern Idlib province, near the town of Sarmada.

“I want to draw attention to the fact that the initial report oddly coincided with Thursday’s concert of the Russian Mariinsky theatre musicians in Palmyra, conducted by Valery Gergiev.

“The initial report itself cannot be found on the website of the Syrian Observatory, it’s just not there. Only a post on Facebook without time or date of the report, which was surprisingly quickly found and broadly disseminated by a Reuters correspondent, who himself was at the time in neighboring Lebanon.

“Notwithstanding all this, the report was quickly taken up by international mass media and even drew comments from officials from the UN, US and UK.”

Konashenkov said there was no information to support the claims that the attack was carried out by Syrian President Bashar Assad’s forces.

UK Foreign Secretary Philip Hammond was one of those who rushed to blame the bombing on the Syrian government.

“The Assad regime’s contempt for efforts to restore the cessation of hostilities in Syria is clear for all to see,” Hammond said in an official statement on Thursday.

Meanwhile, the Syrian government has released an official communique rebuffing claims that the Syrian Army conducted airstrikes at the refugee camp near Sarmada, Sana news agency reported.
