Terrorists Within our Borders

My ears perked up at this line last night in the president's speech about Afghanistan. It's one sentence that has potentially huge implications:

This is no idle danger; no hypothetical threat.  In the last few months alone, we have apprehended extremists within our borders who were sent here from the border region of Afghanistan and Pakistan to commit new acts of terror.

Surely this is not a reference to the Somali gangs rounded up here and in Canada. "Last few months," "within our borders," "sent here ... to commit acts of terror."

Whoa. I'll do some digging but if any readers have some insight into this please let me know.
