""Citing security concerns for the crackdown, Cairo said some of the gunmen who killed 16 Egyptian soldiers near the Gaza border fence in August had crossed into Egypt via the tunnels.""

SOME of the gunmen?

This just gets better! So, how did the gunmen who didn't come through the tunnel get there, if they were Hamas, or Palestinian?
The tunnels are the ONLY way out of Gaza!

That surely points more toward Hamas not being involved.
