Not just another tunnel collapse

A small item in the Palestinian Arab Firas Press website (Arabic): Witnesses said that a Hamas tunnel collapsed today in the Atatra area north of Beit Lahiya. Witnesses said the Hamas gunmen sealed off the area in order to help rescue and evacuation. There have been no shortage of tunnel collapses, and dozens have been killed this year while smuggling in or building tunnels. So what makes this story so special? This tunnel is not in Rafah. It is in Beit Lahiya. Beit Lahiya is also a border town, but it does not border Egypt. It borders Israel. Somehow, I don't think that Hamas is building tunnels to smuggle in supplies from Israel. It sounds more like they want another few Gilad Shalits.
