NASHVILLE, Tenn. (AP) -- Hundreds of people have gathered in Nashville outside the state Capitol to protest the fatal shooting of a black unarmed Florida teen by a neighborhood watch captain.

The Tennessean reported that many of those who attended the rally Saturday were dressed in hooded sweat shirts, the same clothing worn by Trayvon Martin, 17, when he was fatally shot February 26 in the Florida town of Sanford.

Neighborhood watch captain George Zimmerman has claimed self-defense in the shooting and has not been charged.

State and federal authorities are investigating.

The shooting has spurred protest rallies across the nation, with at least three others planned in Tennessee. The Commercial Appeal reports Memphis activists plan two events this week to protest the boy's death and WDEF-TV reports a march is planned in Chattanooga
