Tunnel watch

Interesting story from the Jerusalem Post, but how should I feel about it?
Should I be encouraged by this?

The 150-meter-long tunnel was discovered by Palestinian Authority security forces on Monday and was immediately reported to the IDF, which sent an Engineering Corps force to destroy the structure.

IDF sources and defense officials said Tuesday that the tunnel had been found empty and that it was unclear what its purpose was.

Or discouraged by this?

The Post learned on Thursday, however, that several hundred kilograms of explosives and arms were found in a branch of the tunnel and that the PA security forces confiscated it before informing the IDF of the discovery.

Israel Matzav says I should be discouraged:

Let’s stop right there for a minute. WHERE did all of those weapons go? Obviously, back to the ‘Palestinians’ who put them there, which shows us all the limits of ‘Palestinian’ cooperation with the IDF and the security forces

Plus he shares some informed speculation what the purpose of the tunnel was.

This is the second recent escalation in the business of tunneling. Hmm, will the PA follow the lead of Hamas and start regulating them?

Seriously though, this suggests that Hamas is exporting its tunneling technology to PA areas.
