Ukraine's pro-Russian rebels on Thursday blamed the Western-backed authorities in Kiev for a trolleybus shelling in the separatist stronghold of Donetsk that killed 13 people during the morning commute.

The "foreign ministry" of the self-proclaimed Donetsk People's Republic said the attack "provides further evidence of the barbaric crimes being committed by the Kiev leadership" and called for an investigation by the United Nations and the Organization for Security and Co-operation in Europe (OSCE).
