A woman was killed in downtown Washington, D.C., on Monday when her bicycle collided with a National Guard vehicle that was part of the security motorcade for the ongoing nuclear summit, authorities said.
The collision took place shortly after 6 p.m. at the intersection of 12th Street and New York Avenue - about five blocks from the convention center where world leaders from nearly 50 nations are gathered for the two-day summit.
A brief statement from the summit's Joint Information Center offered no details on whether the cyclist hit the 2-and-a-half-ton truck, often referred to as "deuce and a half," or if the truck ran into the woman.
The gathering at the Walter E. Washington Convention Center in the nation's capital began Monday. It is considered an unprecedented effort to rally global action on securing vulnerable nuclear materials.
It also is the centerpiece of a major objective by President Obama that aims to prevent the spread of nuclear weapons and technology.
