San Francisco - Security Breach at SFO T-3 right now (5/4 - 5:15 AM PST)

A friend of mine is at SFO currently and they're not letting anyone inside T-3 or Intl. Terminal G due to a security breach. He says TSA says it could be up to 2 hours. No other details, UAL.com doesn't seem to reflect this, nor does SFGate.com.

Just saw this on NBC, It seems someone went through security without checking, so they took everybody out to recheck again. Arent there cameras?
