After investigations by Norwegian intelligence in cooperation with US and British intelligence, three men with residence in Norway were arrested on 8 July 2010 in what was described as part of the largest terrorist network uncovered since the September 11 attacks.[2] The men were thought to be part of an Al-Qaeda cell in Norway with links to the network responsible for the 2009 New York City Subway and United Kingdom plot,[3] and were charged with conspiracy to commit one or more acts of terrorism in Norway.[2][4] The plots were thought to have been ordered by Saleh al-Somali, and to have had links to Adnan Gulshair el Shukrijumah.[5][6] At least two of the suspects had regularly attended the Muslim Cultural Center in Sarpsborg, a radical mosque known for its militant views.[5][7][8]
