THOUSANDS gathered in Madrid last night for an emotional service to remember the train bomb victims as Britons were put on alert for possible attacks in the UK.
Around 5,000 mourners, led by Spain's Queen Sofia, filled Madrid's Almudena Cathedral for the memorial service for the 201 people who died in the blasts.
Spanish police are reportedly hunting five new Moroccan suspects they believe were involved in the attacks.
Meanwhile, Britain's most senior police officer said terrorist outrages in the UK were "inevitable".
Metropolitan Police Commissioner Sir John Stevens urged the public to be on the look-out for anything suspicious, warning pubs, clubs, and public transport were all potential targets.
