British Prime Minister Gordon Brown says the peace process in Northern Ireland will not be de-railed by the murder of two British soldiers at an army base at the weekend.After meeting politicians from all communities, Mr Brown said the whole of Northern Ireland felt revulsion at the killings outside Massareene barracks in County Antrim. He said: “What I have seen this morning is the unity of the people of Northern Ireland and its political parties. They stand united behind peace and the political process that they have been building for many, many years, that they are going to continue working together and they want to send a message that the political process will not and never will be shaken. In fact the political process is now unshakeable.” A splinter group of the largely disbanded Irish Republican Army, calling itself The Real IRA, had claimed it carried out the attack. On Monday the leader of the IRA’s political wing condemned the killings and said the peace process will continue. Gerry Adams, leader of Sinn Fein said: “Just to make it clear, the people who carried out this attack don’t have any support within the broad Republican family. And that Sinn Fein will go toe-to-toe to make sure there is no ambiguity in the fact this action should not have taken place.” Floral tributes have been laid outside the military base where the two soldiers, Mark Quinsey and Cengiz “Patrick” Azimka, were gunned down. A hunt is underway to find their killers and an investigation is probing how security around the base had been breached.
