A Europe-wide sweep disrupted an Islamic cell that was recruiting potential suicide bombers for attacks in Iraq and Afghanistan, Italian police said, announcing the arrests of 20 terror suspects. Police said the suspects, mostly Tunisians, were arrested across Europe as part of the sweep against a cell based in the northern Italian region of Lombardy. Police said they found al-Qaida manuals for making explosives, detonation devices and poisons, as well as instructions on guerrilla techniques.
