UK Home Secretary Amber Rudd confirmed that the suicide bomber who killed over twenty people in Manchester by exploding a nail bomb on Monday recently returned from Libya, where he learned how to make sophisticated explosives. GCHQ have significant ongoing operations in Libya alongside US counterparts, which include monitoring all communications across the nation in a bid to assist troops fighting against Da’esh. There is a shortage of human sources on the ground in Libya, so agencies that collect signals intelligence are given greater prominence in the region.
