LONDON: Technology companies must cooperate more with law enforcement agencies and should stop offering a "secret place for terrorists to communicate" using encrypted messages, British interior minister Amber Rudd said on Sunday.
Local media have reported that British-born Khalid Masood sent an encrypted message moments before killing four people last week by ploughing his car into pedestrians and fatally stabbing a policeman as he tried to get into parliament in an 82-second attack that struck terror in the heart of London.
