After Russia bombs own city, explosive found at same site

Seventeen apartment buildings were evacuated Saturday in a Russian city near the Ukrainian border after an explosive device was found at the site where a bomb accidentally dropped by a Russian warplane caused a powerful blast this week, authorities said.
The bomb blast late Thursday rocked part of Belgorod, leaving a large crater and three people injured. The Russian Defense Ministry quickly acknowledged that a weapon accidentally released by one of its own Su-34 bombers caused the explosion.
The ministry said an investigation was underway but did not elaborate on the details of the weapon, which military experts said likely was a powerful 500-kilogram (1,100-pound) bomb.
