By Conor Humphries BALLYMENA, Northern Ireland (Reuters) -Violence erupted in different parts of Northern Ireland for the third successive night on Wednesday, with masked youths starting a fire in a leisure centre but unrest in the primary flashpoint of Ballymena was notably smaller in scale.

The Police Service of Northern Ireland (PSNI) condemned last night's fourth consecutive night of disorder in Northern Ireland, which has resulted in more injured officers, as well as more arrests. In a statement on Friday morning, June 13, the PSNI said there was "significant disorder and violence" in Portadown, Co Armagh on Thursday night.
