'Attack does not seem to be planned carefully'

manchester - The attack in Manchester does not have the characteristics of a carefully planned, complicated attack, with multiple officers, extensive surveillance and advanced exotic explosives. That's what an American official told Reuters press office.

'What is so worrying about these kinds of things is how simple it is to kill, injure and terrorize innocent people without distinction. The US is now plotting- with our partners- all available information to see if we missed something. '
