Egyptian media report that a large factory for manufacturing rockets in the Sinai was discovered and destroyed by security forces.Authorities said that the rockets were being manufactured for the Ansar Beit al-Maqdis jihad group.
Five tons of explosive materials were discovered and destroyed.
Egyptian security officials have always claimed that Hamas and Gaza terror groups were involved in Sinai terror activity. While those claims often seem exaggerated in their hate for everything related to the Muslim Brotherhood, in this case it seems that they are onto something. It seems likely that the Sinai jihadists have learned rocket manufacturing techniques from the Gaza terror groups.
Which means that the Egyptian crackdown on tunnels and travel between Gaza and Sinai really does have a solid security rationale behind it.
