It is a grave breach of international humanitarian law as laid down in the 1977 protocol to the Geneva Conventions. We have video and eye-witness evidence of what was happening. We even have video, taken from the Israeli side, of Israeli civilians watching Abed's car being destroyed. Some of them were carrying children. News teams working in dangerous places deserve protection.
War is an inherently dangerous business.
But we didn't blunder into a battle that day. We were targeted on an otherwise peaceful road. We owe it to Abed and his family to find out exactly how and why it happened. Armies should not be able to get away with killing civilians. And if soldiers have broken the laws of war, they should be punished.
