UN Security Council honors victims of London attack

Opening a meeting dedicated to discussing Somalia, British Foreign Secretary Boris Johnson urged colleagues to "pay tribute to the memory of yesterday's attacks and to all the victims of terrorism across the world."

British authorities said the perpetrator of the attack was born in Britain and known to intelligence services because of suspected links to Islamist extremism.

He was shot dead outside parliament after killing three people -- a policeman and two pedestrians.

The Islamic State group has claimed responsibility for the attack.
