Last night 6 mishgichei kashrut working in the farms in Jordan (established there to provide vegetables from abroad due to the shmitta year making it difficult to provide local Israeli vegetables) were attacked by Arabs. It seems these Arab workers attacked the mashgichim with stones and axes.

Local police were called to the scene,. They came and protected the mashgichim and transferred them to the border-crossing with Israel.

According to the reports, it is unclear what the Arab workers were angry about, but it seems it was the result of some financial dispute.

All I have to say about it is that this was something that was easily foreseen. Somehow they who set this enterprise up thought it would be a good, and cheap, idea. They thought they could trust the Arabs there and that they would be safe. I would also note this is not the first incident, though it seems to be the most serious so far (that I have heard of).

I am surprised they thought this would be a good idea.
