Breaking: Sinai Jihadis deploy surface-to-air missiles

Okay, it's only been reported on Twitter, but it sounds likely to be true. Sinai jihadis have deployed surface-to-air missiles for the first time. I'm going to post a series of tweets by Michael Hanna below. Michael is a senior fellow at the Century Foundation in New York City.

It'll be overshadowed by the other major news in Egypt, but successful deployment by Sinai jihadis of surface to air missiles is a big deal.

.@omar_dawoud @RenaNetjes I assume he just means Russian version of shoulder-held SAMs and was using Stinger as shorthand.

@salamamoussa I know for sure it is legitimate.
