BELFAST - Northern Irish republicans threw petrol bombs at police and hijacked and burned vehicles after a major Protestant parade passed close to Catholic areas of the city of Londonderry on Saturday.
Seven people were arrested and charged with rioting and petrol bombing after the annual Apprentice Boys parade and a protest by republicans nearby.
Pro-British Protestants march every summer to commemorate historical events, particularly notable British military victories, sometimes triggering a violent response from mainly-Catholic Irish republicans.
Thousands watched the parade by some 10,000 Apprentice Boys on Saturday. Afterwards republicans threw petrol bombs at police and attacked armored police vehicles.
