A 40-year-old British woman was being quizzed last night by detectives as part of an investigation into an alleged plot to blow up an Italian synagogue. Counter-terrorism officers swooped on an address in south London just before dawn yesterday after intelligence from Italian police suggested she had been discussing weapons and explosives on Facebook with a suspected Islamic extremist accused of planning an atrocity in Milan. Last night Scotland Yard was liaising with Italian police to establish whether the woman was linked to Mohamed Jarmoune, 20, who was arrested yesterday in Brescia, northern Italy. 'Target': Italian detectives believe the woman may have been in contact with a man involved in an alleged terror plot to attack Via Della Guastalla synagogue in Milan
