Further prayers in Northern Ireland
Updated on 15 March 2009
Prayers for peace and unity have been said in Northern Ireland after rioting broke out between police and republicans.
Petrol bombs were thrown at police investigating the murder of two British soldiers after they arrested leading republican Colin Duffy.
He is one of four people being questioned in connection with the soldiers' deaths.
A further five are still being held over the death of policeman Stephen Carroll.
