Boris Johnson asks internet services to be vigilant; UN mourns attack

Secretary-General Antonio Guterres condemned the attack on Westminster

Internet and social media service providers must "invigilate" against content promoting hate and terror on the internet and take them down, British Foreign Secretary Boris Johnson told reporters on Thursday after the Security Council had mourned the victims of Wednesday's terrorist attack in London with a moment of silence.

The tide is turning against terrorists and the world is standing by his country in the aftermath of the attack targeting its Parliament, he said.

"An attack on London is an attack on the world," he asserted after presiding over the Council session.

He said that the British parliament had been attacked or centuries by various enemies but had withstood them all because stood it for freedom and democracy and was "stronger than that its adversaries."

Meanwhile, Secretary-General Antonio Guterres has condemned the attack on Westminster, his deputy spokesperson Farhan Haq said. "We extend our sincere condolences to the victims and their families, and express our solidarity with the people and the Government of the United Kingdom."

Johnson referred to the recent meeting of leaders from around the world to strengthen the campaign against the Islamic State (ISIS) and said that it showed that countries, including Muslim ones, were coming together to defeat the terrorist organisation.

He said that together they were exploding the myth of the caliphate. The number of people who were going to join the ISIS was dwindling and the tide was turning against it, Johnson added.
