VUHLEHIRSK, Ukraine (Reuters) - A government-held town in east Ukraine sandwiched between two rebel-controlled areas came under heavy shelling on Monday, a day after the start of a ceasefire that Russian-backed separatists say does not apply there.

A Kiev military source said four Ukrainian soldiers had been killed and 21 wounded since the internationally negotiated ceasefire came into force on Sunday.
