Boy, 5, held hostage by gunman in bus shooting

A standoff in rural Alabama went into a second full day as police surrounded an underground bunker where authorities said a retired truck driver was holding a 5-year-old hostage he grabbed off a school bus after shooting the driver dead.

A normally quiet dirt road was teeming with activity around the siege that began late on Tuesday. More than a dozen police cars and trucks, a fire truck, a helicopter, officers from multiple agencies, media and at least one ambulance crowded the stretch where the dead-end residential road branches off a US highway near Midland City, which has a population 2,300.
