New graphic footage has emerged showing armed men killing their captives in the northwestern Syrian city of Aleppo simply for supporting President Bashar al-Assad.

The two-minute video, posted on YouTube and reported by the AFP, shows armed men killing elder members of the Syrian al-Berri tribe.

Amnesty International has already warned about reports of “summary executions” in Aleppo, calling them serious violations of international law.

This comes as the Syrian government earlier said that the armed rebel groups backed and funded by Saudi Arabia, Qatar and Turkey are committing “horrific crimes” against civilians in the capital, Damascus, and the city of Aleppo.

In two letters addressed to the head of the UN Security Council and the UN secretary general, the Syrian Foreign Ministry said the imsurgents backed by Saudi Arabia, Qatar and Turkey are using civilians in Aleppo as human shields, and killing anyone who does not support their crimes.

The Syrian government says foreign-sponsored ‘outlaws, saboteurs, and armed terrorists’ are behind the unrest.
