British Prime Minister David Cameron (R) and London Mayor Boris Johnson take part in a wreath laying ceremony in London’s Hyde Park on July 7, 2015, in memory of the 52 victims of the 7/7 London attacks. Britain on Tuesday marked 10 years since the London bombings with a minute’s silence for the 52 victims, less than a fortnight after an attack in Tunisia highlighted the ongoing Islamist threat.
