One of the two men who have been arrested in connection with the murder of Northern Ireland prison officer, David Black has been named as Irish republican Colin Duffy. David black was killed instantly yesterday, when he drove into a hail of bullets while driving on the M1 to work at Maghaberry Prison. Politicians have blamed the attack on militant nationalists who have been actively targeting prison officers and are opposed to the peace process.

The two arrested men, aged 31 and 44, were detained in the Lurgan area in County Armagh this morning and have been taken to Antrim Serious Crime suite for questioning.

Mr Black, a father-of-two from Cookstown in County Tyrone, had worked at the prison for 30 years and is the first prison officer to be murdered in Northern Ireland in almost 20 years. The high security Maghaberry Prison, which house terrorists, has seen many long running protests over conditions inside the prison. And the Stormont Deputy First Minister Martin McGuinness insisted the murder would not destabilise the peace process.

Ministers from the Northern Ireland Executive and the Irish Republic's government will discuss the murder at a North South Ministerial Council meeting in Armagh today, according to the BBC.
