WASHINGTON - The National Air and Space Museum in Washington is expected to re-open today after being closed Saturday because of an anti-war demonstration.
Protesters swarmed the building to protest a drone exhibit and security guards used pepper spray to repel them, sickening a number of protesters.
Smithsonian spokesman John Gibbons says 100 to 200 demonstrators tried to enter the museum.
He says when a security guard stopped them, saying they couldn't bring in signs, he was apparently held by demonstrators.
Gibbons says a second guard used pepper spray on at least one person and the crowd dispersed.
Medics treated or evaluated a dozen people at the scene but no one was seriously hurt.
A number of those who showed up at the museum were members of the October 2011 Stop the Machine demonstration in Washington, which has an anti-war and anti-corporate greed message.
Others were part of Occupy D.C. -- a group modeled on the Occupy Wall Street movement in New York City.
