Oh look, more documented war crimes committed in broad daylight that Israel will refuse to investigate and will threaten anyone who tries to prosecute their leaders for them.
Have you considered that maybe he was talking with the convoy to coordinate movements or was receiving aid? The LAF is the authority in the area and responsible for security in the country. The red cross would talk to them to secure access and ensure mobility for the aid. Israel is not fighting the LAF. They just want to kill. There are at least 3 well IHL defined war crimes in this event alone.
