Killer of US teacher in Abu Dhabi acted alone: security source

A woman from the United Arab Emirates who stabbed a US teacher to death at an Abu Dhabi shopping mall acted alone and targeted her victim randomly, a security source said today.
The woman, who was arrested following last Monday's attack and the planting of a makeshift bomb outside the home of an American doctor, had no links to "terrorist" organisations, the source told the official WAM news agency.
