GREENBELT, Md. (WUSA) - Prince George's County Fire Department Spokesperson Mark Brady says three tour buses, including one with middle school students from Dallastown, Pa. headed to D.C. for sightseeing, were involved in collisions on the Inner Loop of the Capital Beltway in Greenbelt on Wednesday morning.

Brady says that the Beltway traffic slowed down before the BW Parkway and a box truck hit the back of a bus, causing damage to the engine and disabling the bus.  

Brady also says two separate crashes involving the two other buses happened on the Beltway near Kenilworth Avenue.

Eight passengers/students from the first collision complained about neck and back pain, according to Brady, and four students and one adult from the second collision complained of illness or injury. He says no injuries were reported on the third bus.

Jerry Seinfeld is back and performing stand-up at the Kennedy Center Concert Hall this August.

Seinfeld has a unique style of stand-up that allows him to joke about the little things in life that everyone can relate to. Unlike other comedians, Seinfeld doesn't use a lot of profanity, which is great when you want to bring your parents!

He will be at the Kennedy Center for three shows beginning August 3.

Tickets go on sale on Friday, May 18 at 10 a.m. with prices ranging from $69 - $88. 

Tickets are also available online at www.kennedy-center.org or at the Kennedy Center Box Office (2700 F Street NW)  or by phone 202-467-4600.
