An anti-Israel protest has shut down the southbound lanes of the Golden Gate Bridge in one of many blockades in the U.S. today. 

An online group says they will create traffic blockades and stop shipping activity at ports around the world today.

The protesters chained themselves to a Boeing plant in St. Louis, Missouri this morning.  They also blocked and entrance to a jet-engine plant in Middletown, Connecticut and shutdown the main highway outside Chicago O’Hare airport.
