The show-down over the damaged aid convoy west of Aleppo is reaching comedy level.
The UN/Syrian Red Crescent convoy came from the government held west-Aleppo. It had reached a Syrian Red Crescent center in Umm al Kubra in the "rebel" held area further west where it started to unload. Something happened and many of the trucks burned or where otherwise damaged. Allegedly some 20 people were killed. The incident happened shortly after the ceasefire had officially expired. US sponsored "White Helmet" propaganda teams where there when or shortly after the incident happened.
Here are various claims that were made about the incident (I am time restricted and will for now not provide links for each of these):
The US and its allies claim that the convoy was bombed in an air attack. The Russians deny that they or the Syrians executed any such attack.
The "rebels" had various versions. Syrian jets AND helicopters did it; "Barrel bombs" were used; a sustained attack over hours ...
US Secretary of State first claimed that the Syrian did it, than that the Russians did it; helicopters had attacked. The Pentagon then came up with two Russian SU-24 fixed wing aircraft as the culprits. But the US then claimed that the attack went on over two hours which is longer than a pair of SU-24 could sustain.
