DONETSK, Ukraine (AP) — Dozens of dead insurgents lay piled in a van outside a morgue Tuesday, and a rebel said more were on the way. Bomb disposal experts disarmed a mortar round lodged in a corpse. A wrecked and blood-soaked truck at the Donetsk airport showed the grisly aftermath of battle.

The fight for eastern Ukraine seems to have taken a ferocious turn, as both sides step up their attacks after the rebellious regions mostly boycotted a presidential election that delivered a decisive winner.
