Not looking good right now. A US Ambassador was killed, more than 1 US Embassy is being attacked.

A US Embassy is the property on the United States of America.

Embassy soil is United States soil. Will be interesting to see how this unfolds and what is done.

The Navy is moving closer.

The United States deployed a group of Marines called a Fleet Antiterrorism Security Team to Libya to help secure U.S. facilities, two U.S. officials said Wednesday. Such units are specially trained to retake or guard diplomatic installations and other U.S. facilities in troubled regions.
About 50 Marines were headed to Tripoli and could deploy elsewhere in Libya after their arrival, U.S. officials said.
Other U.S. troops and units abroad have been notified they could be ordered to move to embassy installations around the world to provide additional security, a senior U.S. military official said.
