U.K. - The home secretary, Amber Rudd, who will attend this morning’s emergency Cobra meeting, has added to the tributes to emergency services: This was a barbaric attack, deliberately targeting some of the most vulnerable in our society – young people and children out at a pop concert. My thoughts and prayers go out to the families and victims who have been affected, and I know the whole country will share that view. I’d like to pay tribute to the emergency services who have worked throughout the night professionally and effectively; they have done an excellent job. Later on this morning I will be attending Cobra, chaired by the prime minister, to collect more information, to find out more, about this particular attack, and I can’t comment any more on that at the moment. The public should remain alert but not alarmed. If they have anything to report, they should approach the police. But I have two further things to add. The great city of Manchester has been affected by terrorism before. Its spirit was not bowed; its community continued. This time it has been a particular attack on the most vulnerable in our society. Its intention was to sow fear; its intention is to divide. But it will not succeed.
