单选题 Greysteel, Northern Ireland--Protestant (新教的) gunmen shouting "trick or treat" walked into a Northern Irish shop and killed at least seven people to avenge (报仇) the bombing of a protestant shop one week ago.
Eleven people were wounded, several seriously, when the two gunmen walked into the crowded Rising Sun pub in Greysteel, some 120 kilometres northeast of Belfast, carrying guns.
It is said that they went near a frightened teenage girl and one made the old "trick or treat" greeting that children worldwidely use to get sweets from their neighbours. "I don' t think that's funny," she replied, then she was shot down.
The dead included an 82-year-old man, a 52-year-old woman and the 19-year-old girl who had received the "trick or treat" offer.
The shooting brought the death since Saturday's IRA Belfast bombing to 23. Six Catholics (旧天主教教徒) were killed by protestant death team in the past week.
It was the second time since Thursday that protestant gunmen had struck outside Belfast, which faces North Sea Strait on the east.
