Ukraine says separatists’ rockets incinerated civilian convoy

KIEV, Ukraine — A line of cars and minibuses carrying civilians out of embattled eastern Ukraine was hit Monday by what Kiev authorities said was separatist rocket fire that killed dozens.

The Grad rocket strike set the convoy on fire as it traveled east from towns near the city of Luhansk that were recently recovered by Ukrainian government forces. The vehicles were incinerated by the blast, and their occupants had no chance to escape, a Ukrainian security official told journalists in Kiev.
